Any of this sound familiar?

…Ten minutes after getting to your in-laws, your mother-in-law hugs you and says, “Wow, you look so tired!” 

…You set your dish on the table and your FIL says, “Is this the gluten-free… dairy-free… whatever ‘thing’ you’re doing now?”

…Your SIL glances at your outfit and says, “Oh! You didn’t dress up this year? That’s… cozy.”

And for the rest of the evening, your MIL is slipping the kids cookies while reminding them that grandma’s house is the fun house! She brushes off your requests, overrides your parenting, and you end up playing defense through the entire family gathering. 

Which leads to some fairly *uncharitable* thoughts on your part, like…

Lord, give me patience… because if You give me strength, I will use it improperly.

I know you think your son is the best thing since sliced bread, but he did not come factory-installed with flawless behavior. I’ve seen the man leave wet towels on the bed. Heck, I’ve seen him negotiate with a 3-year-old and lose.

Why is she my mother-in-law? Are you punishing me, God?

And frankly, this has been going on a while. She purposefully doesn’t invite you to gatherings with other girls in the family (and sends pictures afterwards), goes overboard on the gifts (and gets upset when your kids don’t react the way she wants them to), and getting your husband to help you with any of it puts a strain on your marriage. 

Especially during the holidays, in-law dynamics can feel like emotional Jenga, one wrong move and the whole family gathering could crumble. But you don’t have to lose your peace, your joy, or your sanity to survive another family gathering. Really. There is a way to be kind without being a doormat, to stay grounded and calm without needing to go to confession.

In this post, we’ll take a look at why these relationships feel so hard, especially this time of year and what you can actually do to keep your peace, set holy boundaries, and walk away from the holidays without a single new item for confession.

What’s actually going on here?

Before we talk about practical strategies or boundaries, it helps to understand why these moments with in-laws feel so intense, so fast. One of the biggest mindset shifts in navigating extended family is learning the skill of differentiation or the ability to stay rooted in your identity, your values, and your emotions, even when someone else is having big reactions of their own.

Most of us have never heard the word “differentiation”… but we’ve all felt the lack of it.

It’s when:

• You feel responsible for keeping everyone happy.
• You adjust your behavior to avoid someone’s comments.
• You shrink, tense, or over-explain so they won’t be upset.
• You second-guess your parenting because they disapprove.
• You try to “keep the peace” by staying small, quiet, or agreeable.
• You feel instantly defensive over a comment about your food, your kids, or your home.
• You adjust your behavior so no one gets upset.
  

But the thing is… when you actively and consistently take responsibility for someone else’s feelings, you abandon responsibility for your own. You end up abandoning your needs, your values, and your boundaries and then leave gatherings feeling tense, misunderstood, and miserable.

Differentiation helps us decipher what is and isn’t our responsibility to hold. It’s a skill that allows you to not lose your sense of self when someone else is emotional or being hijacked by other people’s reactions.

Because ultimately, we are not responsible for the opinions, preferences, reactions, or disappointment of other people (be it your MIL, your spouse, or your kids). 

We ARE responsible for our own peace, virtue, integrity, and family’s well-being. And one of the best ways to get there is by cultivating the skill of differentiation.

Here is the fast-track way to build this skill:

1—Awareness: We start by noticing the exact moment you start to get pulled out of yourself (when your chest tightens, your stomach drops, or your thoughts start racing). Most conflicts don’t begin with words; they begin with a body cue that something feels threatening or disrespectful.

For example, your MIL says, “Wow… you look tired,” and suddenly you feel heat rush to your face or the urge to defend yourself. That physical reaction is your nervous system telling you, “Something about this feels unsafe or triggering.” This doesn’t fix anything, it just helps us notice what’s happening inside before responding to what’s happening outside you.

2—Disentangling responsibility: This is the practice of separating your responsibility (your tone, your choices, your boundaries) from their responsibility (their emotions, reactions, preferences, or disappointment). Many moms unintentionally carry the emotional load for the entire room by trying to keep the peace, avoid conflict, or prevent anyone from being upset.

For example, when your MIL sighs dramatically because you won’t let the kids have more cookies. You instantly feel frustrated, tense, or pressured to change your mind. But her sigh is her feeling, not your cue to abandon your values.

When these moments happen, it’s nice to have a go-to phrase to ground yourself:

• “Her reaction belongs to her. My boundary belongs to me.”
• “I am allowed to be the parent even if she doesn’t like it.”
• “I don’t have to fix her disappointment.”

3—Nervous system regulation: This is how you keep from yelling, snapping, shutting down, or spiraling. Regulation means tending to your physical state so you don’t act from fight-or-flight. Your body almost always reacts before your brain does. Regulation brings your thinking mind back online so you can respond from values instead of anxiety.

For example, when your FIL makes a snarky comment about your food (“Is this another gluten-free thing?”), you might feel the familiar rush of tight shoulders, heat in your face, or the desire to defend yourself. Instead of firing back or stuffing it down, you pause, take one slow breath, plant your feet, or gently touch your fingertips together to regulate your body.

4—Pre-deciding your boundaries: Many moms only think about boundaries in the moment, when emotions are already high. Pre-deciding gives you clarity before you walk into the house. It removes the guesswork and helps you choose responses that align with your values rather than your stress.

So, before the gather begins, you decide what your boundaries are how you want to keep them. For example:

• If she offers the kids more sugar after I say no, I’ll calmly repeat the boundary once and redirect the kids.
• If someone comments on my appearance, I’ll smile and say, ‘We’re just glad to be here.’
• If I feel overwhelmed, I’ll take a quick bathroom break to reset.
  

This gives you a script to follow instead of scrambling emotionally. You’ve already decided how you’re going to show up, how to keep a boundary without apologizing, and that your plan (and your peace) matters more than their reactions. (More on boundaries in a minute!)

Mary as model a of peace under pressure

One of the most comforting truths about Our Lady is that she wasn’t a stranger to pressure, misunderstanding, or public discomfort. She lived her life surrounded by situations that could have easily triggered defensiveness and embarrassment, or spike her anxiety.

Yet Mary moved through these moments with an interior steadiness rooted not in perfect circumstances, but in perfect trust. Here is one moment (of many moments!) from her life that show us how she kept her peace under pressure:

The Annunciation & Family Misunderstanding

Mary receives the most astonishing revelation in history—she will bear the Son of God—yet she knows this gift won’t be understood by everyone around her. Imagine trying to explain this to family. Imagine the whispers, the sideways glances, the confusion, the questions she couldn’t answer.

Mary lived inside a family and a community that did not fully understand what God was doing in her. And instead of defending herself, rushing to justify, or trying to “manage everyone’s reactions,” she stayed rooted in what she knew to be true: God was at work, even if no one else could see it yet.

What this teaches us: You do not need everyone to approve of your choices, your parenting, or your boundaries. You only need to be faithful to what God has entrusted to you. It really, truly is that simple. When we look at scripture, God does not ask us to focus on being accepted and having everyone’s approval but loving, knowing, and obeying Him. Mary knew that and we are invited (with her help!) to step into that mindset too. 

Here are a few scripts to choose from to help you keep your calm:

• “I don’t need to explain myself to be faithful.”
• “I don’t need their understanding to follow God’s leading.”
• “I can be at peace even if they are not.”
• “Their reaction doesn’t determine my obedience.”
• “I can stay grounded in truth, even if they misunderstand me.”
• “God sees my heart. That’s enough.”
• “I’m allowed to parent differently, even if they disagree.”

Setting boundaries without drama

Most of the stress around in-laws isn’t actually the boundary itself, it’s the fear of the reaction to the boundary. So, let’s look at what boundaries are and who is responsible for keeping them. 

What boundaries aren’t

Boundaries often feel confusing because we treat them like rules we expect other people to follow. But boundaries do not allow you to:

• control someone else’s behavior
• get your MIL to finally respect your parenting
• convince people to act differently
• make someone change their tone, habits, or opinions
• force the family to agree with your decisions
  

(Though, holy wow, would that be convenient.) Those are wishes, not boundaries. And wishes make you powerless because they depend on someone else changing.

What a boundary Is

A boundary is: A clear statement about what you will do to protect your peace, your values, your children, and your family’s well-being when someone else makes a choice you don’t agree with.

Boundaries are about your behavior, not theirs. That single shift unlocks so much freedom.

Because we often think: “I set a boundary and she crossed it, so it didn’t work.”

But boundaries aren’t meant to control someone else’s behavior. Other people (and maybe especially MILs?) will cross boundaries. That doesn’t make them evil or malicious. It just means they are human and often operating from their values, habits, and expectations.

A boundary isn’t successful because they obeyed it but because YOU followed through. Once you internalize this, boundaries become simple, calm decisions instead of emotional battles.

So How Do We Set Boundaries Without Drama?

Here is the easiest way to set drama-free boundaries: The 3-Line Boundary Script

A healthy, effective boundary needs only three lines:

1. Name what’s happening (Neutral, factual, not emotional.)

2. State your boundary/decision (Short. Clear. No justifying.)

3. State what you will do next (This is what makes it a boundary — not a wish.)

That’s it. No lectures. No explanations. No debates. Let’s walk through real-life examples and see the three steps in action.

Scenario 1: MIL giving the kids sweets after you said no

What you want: No more sugar tonight.

Boundary (3 lines): “I see you’re offering another cookie. We’re not having more sweets tonight. If they’re offered more, I’ll take them to play in the other room.”

Your internal script: I can be calm and firm. Her reaction is hers. My follow-through is mine.

Scenario 2: MIL criticizing your parenting

What you want: No debates about your parenting at the dinner table.

Boundary (3 lines): “I hear your perspective. We’re doing it this way. I’m not going to discuss this further.”
Your internal script: I don’t need her approval to parent confidently.

Scenario 3: Over-the-top gifts your kids can’t handle

What you want: Simplicity + less overwhelm.

Boundary (3 lines): “These gifts are very generous. We’re keeping things simple this year. We’ll choose a few to bring home and leave the rest here.”
Your internal script: I protect my kids from overwhelm, even if adults don’t understand.

Scenario 4: Mealtime pressure (clean your plate, etc.)

What you want: Kids to follow your family’s eating norms.

Boundary (3 lines): “I hear you’re encouraging them to finish their food. We pick when and what the kids eat. They pick if and how much.”
Your internal script: I’m allowed to uphold our family’s values and rules around food.

Scenario 5: Being voluntold to host when you can’t

What you want: A peaceful, manageable holiday.

Boundary (3 lines): “I hear you wanting to gather everyone. We won’t be hosting this year. We’re available for dinner on Christmas Eve if that helps with planning.”

Your internal script: I don’t owe anyone an explanation for what I cannot carry.

Scenario 6: Visits that go too long

What you want: Predictable endings and less chaos.

Boundary (3 lines): “This has been a lovely time. We’re leaving in 15 minutes. We’ll say our goodbyes then.”
Your internal script: I’m allowed to choose what’s best for my family rhythm.

Scenario 7: Unannounced criticism (“Wow, you look tired!”)

What you want: No spiraling into defensiveness.

Boundary (gentle version): “Thanks for noticing. We’re just glad to be here.” (Silent follow-through: You don’t engage further.)
Your internal script: I don’t need to internalize comments that aren’t mine to carry. (Not gonna lie, we love this one a lot. Good advice all around, if we do say so ourselves! 😉)

Take a Moment: What Boundaries Do You Need This Year?

Before we move on (to the actual holding part of boundaries!), pause for just a minute. Boundaries are most powerful when they’re pre-decided (instead of when you’re standing in the kitchen trying not to lose your cool while someone hands your kid a fourth cookie).

So let’s make this practical. Grab a notebook, your Notes app, or the back of an envelope and write down 2–3 boundaries you want to keep this holiday season.

Use these prompts to guide you:

1. Where do I usually feel myself tense up around my in-laws? (That’s a sign a boundary is needed.)

2. What patterns or situations left me frustrated or dysregulated last year? (That’s a sign something needs clarity this year.)

3. What do I want to protect for my kids, my marriage, and my own peace? (That’s the heart of every boundary.)

Then write your boundaries using the 3-Line Script:

• What’s happening
• What we’re doing
• What I’ll do next
  

And remember:

• You don’t need to announce them in advance.
• You don’t need to justify them.
• You don’t need to get buy-in.
• You don’t need anyone’s approval.

Boundaries are not harsh. But they do make it possible to show up with the calm, patient, and anchored presence you actually want to bring into your family gatherings. When you choose your boundaries ahead of time, they’re easier to keep.

What To Do When They Push Back (or Are Rude or Hurtful)

Setting boundaries is one thing. Keeping them (calmly, consistently, and without spiraling) is the real work. Because even when you set clear boundaries, even when you’re calm and kind, even when you do everything “right”… There will still be comments, eye-rolls, and moments that sting.

So, let’s walk through what to do in those moments. 

1. Reset in Real Time

Boundaries aren’t one-and-done—they’re practices. And sometimes you need to steady yourself in the moment to keep them. A real-time reset can be as simple as:

• one slow breath
• relaxing your shoulders
• placing a hand on your chest
• grabbing a glass of water
• repeating your internal script

Give yourself a second to regulate before you respond.

2. Responding vs. Reacting

Your body might react instantly when someone pushes a boundary… but you don’t have to.

Reacting looks like: snapping, defending, over-explaining, lecturing, shutting down, trying to “prove your point.” (It feels justified but drains you later.) Responding looks like: neutral tone, short statements, calm redirection, repeating the boundary once, choosing to disengage.

3. Use the Broken Record Technique

If someone pushes, calmly repeat the same boundary once—no defending, no explaining.

Example:
MIL: “Just one more cookie—it’s Christmas!”
You: “We’re not having more sweets tonight.”
MIL: “You’re so strict.”
You: “We’re not having more sweets tonight.”

If she asks respectfully at another time, then you can choose to explain. But you don’t have to.

4. The Disengage Option

If someone keeps pushing, you don’t need to stay in the conversation. You can change the subject, redirect your kids, move to another room, or simply stop engaging. Disengaging isn’t rude. You’re allowed to remove yourself from an unhealthy dynamic. You are allowed to walk away from a moment that isn’t good for your peace.

5. Know Your Immediate Follow-Through

Every boundary needs a follow-through. This is where most moms lose their peace, not in the boundary, but in the hesitation.

Examples:

• Sweets boundary ignored → redirect kids
• Criticism continues → end the conversation
• Tension rises → take a break
• Visit runs long → gather your things
• Someone escalates → calmly remove yourself or the kids

Follow-through is what turns a boundary into a boundary… not a wish.

How to prepare spiritually before family gatherings

One of the best ways to keep your peace during family gatherings is to anchor yourself before you ever walk through the door. We’ve got a few simple practices that can strengthen your heart far more than white-knuckling your way through a tense moment.

Begin with a short prayer. Nothing long or elaborate—just a quiet turning of your heart toward God: “Lord, go before me. Fill my mind with Your peace and my heart with Your gentleness. Help me stay rooted in You, no matter what I walk into.”

This small surrender shifts your focus from pressure to presence. Then take one slow breath and tie it to Scripture. 

Choose a verse that bolsters you:

• The Lord is my light and my salvation; whom shall I fear? (Psalm 27:1)
• Peace I leave with you; my peace I give to you. I do not give to you as the world gives. (John 14:27)
• Be still, and know that I am God. (Psalm 46:10)
• Cast all your anxiety on him, because he cares for you. (1 Peter 5:7)
• The Lord will fight for you, and you have only to keep still. (Exodus 14:14)
• When I am afraid, I put my trust in you. (Psalm 56:3)
• The Lord is near to the brokenhearted, and saves the crushed in spirit. (Psalm 34:18)
• In returning and rest you shall be saved; in quietness and in trust shall be your strength. (Isaiah 30:15)
• Do not be afraid; stand firm, and see the deliverance that the Lord will accomplish for you today. (Exodus 14:13)
• Trust in the Lord with all your heart, and do not rely on your own insight. (Proverbs 3:5)
  

You are not responsible for how anyone else behaves, only for how you show up. Their tone is theirs. Their choices are theirs. Their reactions are theirs. Your peace, your virtue, your presence, and your responses belong to you. Walk in knowing that God is already there, already working, already strengthening you to meet this moment with grace. “It is the Lord who goes before you; He will be with you, He will not fail you or forsake you. Do not fear or be dismayed.” Deuteronomy 31:8 (NRSVCE)
