We also want to make sure you realize that BPA-free does not mean that the plastics used will not leach estrogenic chemicals into milk, particularly when the materials are stressed (like heated or microwaved). You also want to make sure the bottles promote a good latch and prevent lazy feeding, do not exacerbate nipple confusion, are free of harmful chemicals, and are easy to clean and use. Even more so was the fact that every baby we tested it on readily accepted it and seemed to prefer it over their existing bottles - and that's saying a lot! One of the best ways to help prevent gas and spit-up is to ensure proper positioning during feeding, so definitely check out one of our nursing pillows to help keep your baby upright and make feeding more comfortable for both you and your baby. They use an innovative SkinSoft nipple that has a slight texture to help babies keep the silicone nipple in the mouth, making it quite a bit less slippery than most bottle nipples.

Note that we also tested out the newer model, the Born Free Breeze, but it didn't make the list due to a poor (and collapsing) nipple design. We did recently test out a new stainless steel baby bottle made by thinkbaby, and we loved the concept and not having to worry about plastics leaching chemicals into milk or a glass bottle shattering when dropped.The bottle shape is really unique for a couple of reasons: first, it makes warming the bottle's contents much faster than with a typical bottle because there's not as much volume in a given area, making heat propagate through the milk or formula much faster than with a wider bottle. Reasons for baby bottle leaks can include improper assembly, wrong nipple size, the temperature of the liquid in the bottle or even incorrect feeding position.

These are a recent addition to our best baby bottles list and made a great impression during our hands-on reviews. Overall, because of the potential risks associated with estrogenic chemicals being leached from plastics, we highly recommend glass baby bottles (check out the Dr. Finally, we found them easy to clean (including the vent ring), and we appreciated that they are dishwasher safe and safe to sterilize. Many parents are opting for Philips Avent Natural Baby Bottles because the natural nipple shape makes it easy to combine bottle feeding with breastfeeding.How about the other feature, the fact that you can feed directly from the pouch, using an attachable nipple? So when it's feeding time, you can be confident that the internal vent systems will minimize the risk of gas and bloating for your baby. If there’s still a leak at the bottom, wrap a towel around the base of the bottle to avoid getting milk all over the baby. In a more practical sense, the wide base made it easier to clean, and we also liked the small tab on the side of the wide green base ring, which made it much easier to grip and open or tighten the bottle. Over the past few years, the Philips AVENT Natural bottles have used increasingly thin plastic, though the functionality hasn't seemed to change.

Of course, you will also want the baby bottle to fit any style and color preferences, be compatible with the best breast pumps, and also fit your budget.The nipple on the Munchkin has accordian type ridges in the lower neck portion so the nipple will angle supposedly for better feeding. That said, we found that the nipple and venting system worked very well for bottle-fed babies, and the bottle did a great job minimizing gas and discomfort for babies with more sensitive tummies. In our testing, we thought the valve did a very good job of keeping the flow rate nice and consistent, and also preventing too much air swallowing, burping, and spit-up. This makes it hard at times to figure out exactly how much milk is in the bottle, which can be frustrating.
