A lactation consultant or IBCLC is trained expert in infant feeding. That includes breastfeeding, bottle feeding and exclusively pumping. A baby who is bottle fed may still have trouble transferring milk or formula from the bottle because of possible tongue tie, tight body, bottle refusal and many other reasons. If you're pumping, a lactation consultant can flange fit you. Maybe you have concerns about your baby's weight. Are you going back to work soon? You might even be pregnant and looking to learn what options you have to feed your baby. All these situations a lactation consultant can help you with!
