The first time my mother-in-law suggested I put cereal in a two-month-old’s bottle “to help him sleep longer,” I thought she was joking. She was not joking. She was completely serious and slightly offended that I didn’t immediately thank her for this revolutionary advice from 1987.

“That’s what we did with all four of ours,” she said, with the confidence of someone who has never Googled a choking hazard.

The Greatest Hits of Bad Grandma Advice

I’ve collected these from friends over the years. A highlight reel:

• “Just put some whiskey on his gums.” (No.)
• “Put the baby on their stomach, they sleep better.” (They also die more often this way, Brenda.)
• “A little cereal in the bottle fills them up.” (Or chokes them. Coin flip.)
• “We just let you cry and you turned out fine.” (Debatable, but also not the point.)
• “They’ll sleep when they’re tired.” (So will I, Janet. SO WILL I.)
• “You’re overthinking this.” (You’re underthinking it and also it’s 2026.)

The thing is, these women aren’t trying to hurt their grandkids. They genuinely believe what worked for them is still correct. Because in their era, it WAS the advice. Pediatricians recommended stomach sleeping. Cereal in bottles was mainstream. The research just didn’t exist yet. But Lucille was a stay at home mom for 25 years and didn’t have to go back to work a 6 weeks post partum like you do. She also had an entire freaking village of other women coming in to help her. I did not. In fact, my second son was born and raised in Germany! We literally were alone over here and had no support whatsoever.

Why “Just Ignore Their Advice” Doesn’t Work

Because they don’t stop. And because half the time, they’re saying it in front of your partner, who suddenly looks uncertain. He trusts his mommy after all. Now you’re not just deflecting advice. You’re defending your parenting choices to your spouse because grandma planted a seed of doubt.

A friend once came home from her in-laws’ house and found that her mother-in-law had put the baby down for a nap on his STOMACH “because he seemed uncomfortable on his back.”

She nearly lost her mind. Rightfully.

She told her mother-in-law, firmly, that back sleeping is non-negotiable and explained why. Her MIL burst into tears, called her son an hour later sobbing about how she was “just trying to help” and “clearly isn’t welcome anymore.”

Her husband came to her that night with the classic: “Why can’t you just let her do it? She’s trying to help.”

So she pulled up the research. The AAP guidelines. The studies showing that prone sleeping is one of the single biggest modifiable risk factors for SIDS. She showed him the numbers. He went quiet.

“She’s just trying to help” hits different when the help could kill your baby.

The Scripts That Actually Work

For the pushy advisor: “Thanks! Our pediatrician has us on a specific plan, so we’re following that.” (Invoking the doctor shuts most people down.)

For the offended grandma: “I know you did an amazing job with [partner’s name]. The recommendations have just changed so much since then! Isn’t it wild?”

For the one who won’t stop: “We’ve got it handled. I’ll let you know if we need help!” (Then never let them know.)

For the one who does it anyway: That’s a boundary conversation with your partner. Because if grandma can’t follow the rules, grandma doesn’t do solo bedtime. Period.

The Real Boundary

You don’t owe anyone an explanation for how you raise your baby. Not your mother. Not your mother-in-law. Not the stranger in Target who heard your baby cry for eleven seconds and felt compelled to offer input.

You did the research. You have a plan. You are the parent. Smile, nod, change the subject, and keep doing what works.
