My Relative Insists My Baby Is Autistic

Q&A on what to do

Emily Oster

2 min Read

My sister-in-law keeps suggesting my eight-month-old son might be autistic (which feels inappropriate and annoying to me), but do I need to be looking for signs? He does some things that are “red flags” (I guess? twirls his hands and shakes his head back and forth and isn’t crawling yet) but otherwise seems perfectly happy, social, and smiley. Should I worry? I find myself overanalyzing his milestones now, and I was never the overthinking kind of person and it’s bothering me.

—Triggered by my in-laws

This is extremely inappropriate and annoying.

In thinking about socioemotional developmental milestones, at nine months the CDC suggests most babies can:

  • Show several facial expressions (happy, sad, angry, surprised)
  • Look when you call their name
  • React when you leave (reaching for you, crying)
  • Smile or laugh when playing peek-a-boo

Physical milestones include sitting and moving things between hands (the CDC does not any longer consider crawling an important milestone, since not all babies do it).

Your baby is close to this age (although a month is a long time in baby-land), so this is a list that’s worth keeping an eye on if you’re concerned. If you are either worried or far off these milestones, checking in with your doctor at the nine-month visit is always a good idea. But I think your biggest problem here is your sister-in-law, not your baby.

To that, I think this is a place for boundaries (even if your child is autistic, this applies). I strongly advise you to come up with some closing language to use if she brings it up again. “Thanks for your concern, but we aren’t worried and I’d like to move off this topic.” Or “Thanks for your concern, but his doctor isn’t worried, so we are not.” I can think of some less polite things, too. Don’t let this person get in your head!

Reflux: It’s more common than you think! Comment “Link” for an article by @thepediatricianmom breaking down the information we have about reflux — what it is, what you can do, and red flags to look out for.

This graph shows how reflux changes with age. Nearly half of all babies experience reflux by 3 months, often peaking around 4 months before improving by their first birthday. And remember, if you’re struggling, you’re not alone. The most effective treatment for infant reflux is time. It will get better!

We’re heading into a three-day weekend, which means a lot of you might take the opportunity to do some potty training. 

Here are some things to keep in mind:
🚽 It takes longer than three days (based on the data!)
🚽 Your child will have trouble staying dry at night.
🚽 Poop sometimes comes later than pee – this is common, you just have to work through it.

Trampoline parks: great way to get the sillies out or injury haven? Or both? Comment “Link” for an article breaking down a 2023 study on injury trends in trampoline parks.

Here’s a visualisation based on the paper, showing the injury rate by area. Beware the foam pit and the high-performance areas! Slam-dunking, though, seems fine.

Screens have become a ubiquitous part of classroom life. Is this a good thing? Today on the ParentData podcast, I talk with @jessgrosewrites from the @nytimes. She recently ran a survey asking about kids’ screen usage after not being able to find studies and data on the subject.

“Nothing is all bad or all good. But I think overall, there just has been very little scrutiny into something that has been a massive shift in the way kids learn in the past, let’s say, two decades.”

We surveyed the ParentData audience and here’s what you said about the worst baby products. Bottom of the list: unnecessary warmers. Don’t get your kid used to having warm diaper wipes! Nothing good can come of that.

Comment “Link” for the best baby items and other parenting wisdom from the ParentData community. Best general advice: get things used, and you do not need as much as you think. 

Add your advice below! What do you wish you’d known about in advance, and what was a waste? ⬇️

How do we get our kids excited about math? Can every kid be a “math kid”? Shalinee Sharma of @zearnmath shares her insights on the ParentData podcast. 

When I offered her a magic wand to fix math education, she told me: “We have to pair understanding with memorizing. And the best way to understand really anything, but especially math, is simple pictures, concrete context, just make it feel real, not abstract and theoretical. What’s a negative number? Think about if sea level is zero and then you dive into the ocean, that’s a negative number. And then you climb a mountain, well that’s a positive number… We just need pictures to be a part of mathematics.”

Milestones. We celebrate them in pregnancy, in parenting, and they’re a fun thing to celebrate at work too. Just a couple years ago I couldn’t have foreseen what this community would grow into. Today, there are over 400,000 of you here—asking questions, making others feel seen wherever they may be in their journey, and sharing information that supports data > panic. 

It has been a busy summer for the team at ParentData. I’d love to take a moment here to celebrate the 400k milestone. As I’ve said before, it’s more important than ever to put good data in the hands of parents. 

Share this post with a friend who could use a little more data, and a little less parenting overwhelm.
