I am currently using Baby hug bottle. How will I know which nipple to purchase next. What is the size. now its printed 14 in nipple.

A. hi well , The key to choose the right nipple size is to observe your baby's feeding behavior. but yes there are some general guidelines you can follow for this like: if you want to buy nipple for premature babies or Newborns,start with slow Flow nipple,if baby is 1-3 Months old,you may use medium Flow nipple and if baby is 3-6 Months old consider fast Flow nipple.
