6 Pack BPA Free Polypropylene Classic Nurser Baby Bottles by Evenflo

These polypropylene bottles do not contain bisphenol-A, which may be harmful to babies. Polycarbonate baby bottles have been tested and found that bisphenol-A migrates from the bottles into the milk. Parents are advised to use polypropylene baby bottles instead of polycarbonate (a clear, shiny, glassy-looking hard plastic). Babies are especially at risk as the amount of toxin ingested is large compared to their body weight. Also a baby's organs are still growing and will be affected more than those of a fully-grown person.

When bottle-feeding your baby, make sure the nipple hole is of the right size. If your child appears to be sucking too hard, you probably need a fast/medium-flow nipple. An overly resistant nipple could collapse under your baby's strong sucking motion. On the other hand, if your baby seems to be sputtering and gulping often, your baby could need a slow-flow nipple. For a newborn, you know the nipple size is right when the milk comes out in a spray for a second or two when the bottle is inverted, and then trickles down to drops. Do not attempt to enlarge the hole in the nipple; this may cause tearing and present a choking hazard.

What is the difference between latex and silicone nipples? Both have advantages, and the choice usually comes down to baby's preference. Latex is a very smooth, resistant natural rubber. Latex is soft in baby's mouth and baby may like the way it retains scents, but it doesn't hold up as well to repeated cleanings and little teeth can quickly chew through it. Silicone doesn't wear off or retain odors and is much harder for baby to bite through. Silicone is sturdy and easier to clean although it is not as soft on baby's mouth.
