It was hard enough deciding which stroller, swing, and crib to buy. Now you have to pick a bottle! Shapes of bottles for formula and breast milk vary, from wide ones that emulate the shape of a breast, to more traditional narrow bottles. For babies who are prone to gassiness and discomfort, a bottle with a venting system or a plastic drop-in bag may be helpful.
Choose a bottle that’s free of bisphenol A (BPA), a chemical found in plastics that may be linked to adverse health effects. Glass bottles don’t contain BPA; however, plastic bottles are more lightweight and less breakable. Just make sure to check the label when you’re at the store. It should say the bottle is BPA-free.
Most bottles can adapt to different types of nipples. It is a good idea to have a few different nipples on hand at first to see which one your newborn takes to most readily. For breastfeeding babies, bottle nipples shaped more like the breast may help decrease nipple confusion. However, many babies have no trouble going between breast and bottle.
