Nipple: Start with a clear silicone nipple.
Latex rubber nipples can cause allergic reactions and can contain impurities linked to cancer.
Bottle: Use glass.
Plastic bottles can leach a toxic chemical called bisphenol A (BPA) into formula. Avoid clear, hard plastic bottles marked with a 7 or “PC.”
Plastic bottle liners: Don’t use them.
The soft plastic liners may leach chemicals into formula, especially when heated.
Water: Use filtered tap water.
If your water is fluoridated, use a reverse osmosis filter to remove fluoride, which the American Dental Association recommends avoiding when reconstituting formula. If your water is not fluoridated use a carbon filter. If you choose bottled water make sure it’s fluoride-free.
Formula: Choose powdered.
A toxic chemical called bisphenol A (BPA) can leach from the lining of metal cans and lids. Liquid formulas have higher levels. Powdered formula is a better bet.
