We just interviewed the first day care provider today. One thing she mentioned was that according to NY day care rules, Bottles can no longer be heated in the microwave. We are planning *fingers crossed* that I will be able to pump breastmilk after I return to work. Can you just let a bottle sit out to warm to room temp, or should I consider getting a bottle warmer for the daycare to warm cold breastmilk? We’re planning to use room temp bottles for the most part to make sure our baby won’t refuse if we are out and can’t heat one.

You *can* let a bottle sit out to warm, but it should never sit at room temperature for longer than 4 hours (some websites will say up to 8 hours, but that is usually including thawing time, or accounts for an especially cool room). The safest way to warm breast milk is to either run luke-warm water over the bottle, or set the bottle in a bowl of warm water (in NICU we warm breast milk by placing the bottle in container with warm water).
Here is a website with info on milk storage/warming:

I’ve always heard that warming bottles in a microwave is unsafe for infants. Microwaves heat foods unevenly – it could be really cold in some places and really hot in others (hot even to burn a child). I’ve always warmed bottles in a bath of warm water.

you probably could but it would be tricky – much better and more commonly to either warm refrigerated breastmilk in a warmer or a bowl of hot water. You can “warm” it to just room temp through either of these methods but letting cold milk warm on its own by sitting out is hard because you would need to know well in advance when the baby would be hungry!

I would second guess hiring a daycare which EVER warmed bottles in the microwave. That is just bizarre considering it is common knowledge (and has been for some time) that you NEVER do that.
MB’s daycare had crockpots full of water that were set to High at all times. When they wanted to warm a bottle, they just dipped a cup in to fill with some water, then sat the bottles in the cup to warm. However safety regulations forbid that practice (because kids can pull the crockpot full of scalding water on themselves) so just today they installed bottle warmers in every classroom.
If you are deadset on this daycare, I’d buy them a bottle warmer. You can’t just leave the milk out, and if you feed the baby cold breastmilk a lot of your nutrtious fatty milk gets stuck on the bottle.

I work in a infant classroom and we provide a bottle warmer. We’re not allowed to use the microwave and we’re also not allowed to leave a premade bottle out of the refrigerator for more than an hour, including drink time. I think I would talk to them in more detail about what their normal procedure is because I can’t imagine you’re the only one with this issue. They may have a procedure already in place.

That’s what my family has ALWAYS done for bottle warming.
Our rule of thumb is if it’s been out for more than 1hr it’s down the sink. Better safe than sorry in my opinion.

Yes, you can buy a Munchkin travel bottle warmer from Target for about $15 or so, although in a pinch, the milk can sit out at room temp for a few hours (no longer). Microwaving it causes some spots to heat up more than others and the milk you test on your arm may be a different temperature than milk elsewhere in the bottle. It can cause the poor bebes to burn their mouths. 🙁

It’s surprising to me that the daycare doesn’t already have a bottle warmer they use. What do they do for other babies that need bottles during the day?

When we toured our daycare, they had a rice warmer with some bottles warming in it on the counter. I think they just had the bottles wrapped in towels so there was no water involved.
