If you're having a baby shower, register for a few starter bottle kits from different brands. They come with several of various sizes and nipples. If your baby keeps spitting out or battling with a bottle, or is especially fussy after eating, offer a slower or faster nipple. If that doesn't work, try a premium bottle, such as Born Free or Adiri.
If your baby shows signs of intolerance, such as gas, a rash, persistent vomiting, diarrhea, talk with your pediatrician. You'll probably need to switch formulas, not bottles or nipples, if your baby is formula-fed. If you're predominantly or exclusively bottle-feeding, six 4-to-5-ounce bottles will be a good start. If you're supplementing breast milk with an occasional bottle, you may need only one or two bottles. Once you settle on a nipple, buy about half a dozen.
Some of the best prices you'll find for major-brand baby bottles may be at such retailers as Walmart and Target, but online shopping can also yield bargains, so it's worth shopping around. Major baby stores offer sales, coupons, and newspaper inserts, so watch for them. They may give a 10 to 15 percent discount on different brands of bottles and feeding accessories.
Most nipples are made of latex or silicone; stick with silicone. Buy silicone nipples only if they're clear or brightly colored, not brownish. Silicone is less problematic than latex, because some babies develop a sensitivity or allergy to latex. Clear, odorless, taste-free, and heat resistant, silicone is also less porous than latex, so a silicone nipple may be better at resisting bacteria, which can settle into any textured material. Neither silicone nor latex is made with BPA.
