ABOUT THISOur 0-6 Month Bundle was designed specifically for the early feeding development of newborns to six months. It has 4 different nipple sizes you need to support your baby’s instinctive breastfeeding technique for the first 6 months of life. These varying nipples match your baby’s changing feed rate as their feeding need grows. By using only Minbie teats when a bottle is needed, it protects your baby’s inborn breastfeeding technique - this is best for your baby's digestion and to avoid nipple confusion. Now with our new ultra-premium and durable PPSU bottles, this is the best nipple and bottle offering available to new parents.
