Our 0-6 Month Bundle was designed specifically for the early feeding development of newborns to six months. It has 4 different teat sizes you need to support your baby’s instinctive breastfeeding technique for the first 6 months of life. These varying teats 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 fledgling digestion and to avoid nipple confusion, lazy feeding, reflux & colic.
