Should You Avoid Certain Bras During Pregnancy?

Q&A on breastfeeding

Do you really have to avoid underwire bras/sports bras with thick bands if you are not planning to breastfeed?

—Looking for Support

First, let’s cover breastfeeding. The main concern with underwire or other very restrictive bras is clogged ducts. When you are breastfeeding, the milk ducts in your breasts fill with milk (and empty, and fill, and empty…). During this process, they can become clogged, which can lead to pain and possibly mastitis

These clogged ducts are more likely with compression, as would happen with an underwire bra or a sports bra with a tight band. Wearing a looser bra can help avoid this. You’ll still want a sports bra for exercise, but day-to-day, especially early on, something with less structure is recommended.

To your question: what if you don’t plan to breastfeed? If this is the case, your milk will still come in, but will dry up fairly quickly. During this initial period — in the first day or week after birth — you’ll want to adhere to the same no-underwire rule. Once you are no longer lactating, you do not need to worry about this.

If we are hoping to breastfeed, at what point during pregnancy should we start avoiding underwires and tighter bands? Is it okay to wear an underwire for a few hours (at work for example) as long as we are letting things breathe for the remaining hours of the day?

Seems like advice that’s been extrapolated out of context. Unless your milk’s come in early there’s no reason not to wear whatever you want to when you’re pregnant.

💧 Is your kid drinking bathwater? Here’s the 411: It’s gross but not dangerous! Comment “Link” for my full guide to bathtime.

 A little soap or mold from toys isn’t harmful, and diluted pee is no big deal. Eating a lot of poop can make you sick, but in small amounts, it isn’t toxic.

Bottom line: Bathwater isn’t your kid’s best drink option, but don’t stress too much! Just keep an eye on them during bathtime for safety.

A study shows just how deep the gender divide runs when it comes to household labor—even in something as simple as a phone call. Does this ring true for you? Share your experience in the comments 👇

Ever seen a headline that makes your heart race, but when you dig deeper, the study behind it doesn’t hold up? That’s a panic headline! It’s designed to grab attention and spark fear, but the research it’s based on is often weak or irrelevant. Next time you see one, take a breath, look closer, and don’t let sensationalism get you stressed out.

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.

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.”
