Q&A: Should I Purchase Bottles?
Do I need to buy bottles for my baby?
Not necessarily. Unless you will be away from baby for extended periods of time (like if you are returning to work), you might never need a single bottle. Bottle nipples can sometimes cause babies to have trouble latching for breastfeeding, so you shouldn't feel the need to introduce a bottle “just in case.” It's especially important to steer clear of artificial nipples in the first six weeks or so of baby's life, until breastfeeding is well established.
