Glass vs. Plastic Baby Bottles

Choosing a Baby Bottle continued...

Even if you're concerned about bisphenol A, you don't have to give up your plastic bottles. Non-polycarbonate plastic versions are available. They're made of polyethylene (#1, #2, or #4 recycling symbols) or polypropylene (#5 recycling symbol). Non-polycarbonate plastics are also options when your child graduates to a sippy cup.

Disposable bottle liners are also typically BPA-free (look for the words "BPA-free" on the label). They tend to be more expensive than bottles alone, though, because you have to change them after each feeding.

If you want to try glass bottles but you're concerned about them breaking, some companies make silicone sleeves that go over the bottle to protect it.

Caring for Your Child's Baby Bottle

Here are some tips on caring for your child's baby bottle and reducing potential risks from BPA:

• Never store breast milk or formula in plastic bottles. Pour it into the bottle just before your baby is ready to eat. Throw out anything that is left over.
• Heat and wear can both increase the rate at which BPA leaches out of the plastic. Heat polycarbonate bottles in warm water (not boiling), rather than in the microwave. Microwaves should also be avoided because of the risk of burning baby's mouth. Throw out any polycarbonate bottles that are scratched or cracked.
• Don't use hot water or a harsh cleaner on polycarbonate bottles because this also can cause the plastic to break down more quickly. Instead, use a gentle cleaner and warm water.
• Replace any glass bottles that have cracks or chips in them.

Keep in mind that bisphenol A is also found in the linings of formula cans and can get into the product. You might want to opt for powdered formulas, which typically contain lower levels of BPA than liquid formulas.
