Safety notes
BPA-free and made from polypropylene. Check nipples regularly for tears or damage and replace them every 2-3 months. Always test milk temperature on your wrist before feeding.
Buying guide notes
Start with a 4-pack of the 4oz bottles for newborns and size up to 8oz around 3-4 months. If the extra parts bother you, Dr. Brown's Options+ line lets you remove the vent system once colic improves. Comotomo bottles are a good alternative if you want something with fewer parts.
Overview
Our full take
Dr. Brown's bottles have been around forever, and there's a reason they keep showing up on every "best bottles" list. The internal vent system actually works. It channels air away from the milk so baby swallows less gas, which means less fussing and spit-up after feeds. Our son had terrible colic for the first two months, and switching to these made a noticeable difference within a couple of days. The Natural Flow nipple has a shape that works well for babies going back and forth between breast and bottle. They come in both standard and wide-neck options. Yes, there are extra parts to wash (the vent inserts add two more pieces per bottle), but if your baby is gassy or colicky, you won't care about the extra 30 seconds at the sink.

Frequently asked questions
What's the vent system for?+
The internal vent tube stops air from mixing with the milk, which cuts the gas, spit-up, and colic that air bubbles cause. It's the whole reason these bottles exist.
Aren't there a lot of parts to clean?+
Yes, the vent insert means more pieces than a basic bottle. Many parents drop the vent once colic settles around 3 to 4 months, and the bottle still works fine as a standard one.
Narrow or wide-neck?+
Both exist. Narrow is the classic and cheapest; the wide-neck Options+ is easier to clean and fill. If you're combo-feeding, the wide nipple shape transitions a bit easier.
