Your mother-in-law just handed your five-year-old an iPad at the dinner table. Your dad is feeding your toddler candy an hour before bedtime. Your child looks at you, waiting to see if the rules still apply. You're trying to keep the peace, but you also know that these next few days will undo months of your work.
- Most parents face this: 43% have asked grandparents to change behavior during visits.
- Children feel confused when rules change completely at grandparents' house.
- Pick two non-negotiable rules and let smaller things go this week.
This is the week many parents dread. Thanksgiving gatherings bring joy, but they also bring relatives who think your rules don't matter in their house.
Why is this happening right now?
Holiday visits put grandparents and parents in close quarters for longer stretches than usual. The C.S. Mott Children's Hospital National Poll on Children's Health found that 43% of parents have asked grandparents to change their behavior during visits. When grandparents refused, 42% of those parents limited future visits. This isn't rare. It's most families.
Child psychologists interviewed by Parade identified grandparents undermining parents as a top concern they hear about in their practices right now. The experts explain that when adults openly contradict each other, children feel confused about which rules are real. They may also learn to play adults against each other. The Running Wine Mom published a Thanksgiving week guide in November 2026 with practical scripts, noting that parents are actively searching for help with this exact situation as families prepare to gather.
Why do grandparents ignore the rules I set?
Most grandparents aren't trying to undermine you. They raised their own children with different methods, and those children turned out fine. They may see your rules as overly strict or unnecessary. They want to be the fun ones. They have limited time with your kids and don't want to spend it saying no.
Some grandparents truly believe they know better. Others feel hurt that you parent differently than they did, as if you're criticizing their choices. A few are genuinely unable to keep track of all the rules modern parents follow around screens, sugar, and sleep schedules.

What should I say when my child's grandparent breaks a rule?
Name what just happened in a calm voice. Say it in front of your child so everyone hears the same message. You might say, "We don't do screens at the table. I'll hold onto this until after dinner." Or "Bedtime is in twenty minutes, so this is the last treat." Then redirect the conversation to something else.
If the grandparent argues or rolls their eyes, don't engage in front of your child. Later, when you're alone, you can say, "I need you to support my rules in front of the kids. We can talk about whether you agree, but not in the moment." The Running Wine Mom suggests this type of direct but respectful script for holiday boundary conversations.
Should I let some things go this week?
Yes. Choose two or three rules that really matter to you and let the rest slide for a few days. Maybe bedtime is sacred, but an extra cookie isn't worth the fight. Maybe you'll enforce no hitting but allow more TV than usual.
Your child will be fine if they eat pie for breakfast on Friday. They will not be fine if they see you and their grandparents in open conflict all weekend. Pick your battles based on safety and your family's core values, not on every preference.
What to try this week
- Before you arrive, send a short text or email. Write something like, "We're so excited to see you. Just a heads up that bedtime is 7:30, and we're avoiding screens before bed. Thanks for helping us stick to that." Keep it to two rules maximum.
- Bring your own enforcement tools. If your child has a comfort item for bedtime, bring it. If they need a visual timer, pack it. Don't rely on grandparents to have or remember your systems.
- When a rule breaks, restate it once and move on. Say, "We do teeth before any snacks," and then guide your child to the bathroom. Don't lecture the grandparent or explain why the rule exists. Just do the thing.
- Thank grandparents when they do follow through. Say, "I really appreciate you sticking to the bedtime routine tonight." People are more likely to cooperate when they feel respected, not policed.
- Have a private conversation about the big one. If there's a rule you absolutely need them to follow (like a food allergy or a safety issue), talk to the grandparent alone. Say, "This one isn't negotiable because [brief reason]. I need to count on you for this."
- Build in breaks from each other. Go for a walk with just your kids. Send them to the park with your partner. Everyone behaves better when they're not on top of each other for three straight days.
What progress looks like
You probably won't get perfect compliance. Progress is your mother-in-law asking what time bedtime is instead of just ignoring it. It's your dad giving your kid one cookie instead of five. It's you staying calm when a rule breaks instead of snapping or giving up entirely. Your child sees that you mean what you say, even when it's hard. That's the real win.
When to look closer
If a grandparent repeatedly ignores safety rules (like car seat use or medication), or if they actively teach your child to lie to you about what happens at their house, that's more than a holiday disagreement. If your child comes back from visits anxious or confused about basic rules, or if you're avoiding family gatherings entirely because of this issue, talk to your pediatrician or a family therapist. They can help you figure out whether this is normal grandparent boundary-pushing or something that needs a bigger intervention.
