Hello, Mother must be taught about to breast feed by pediatric care nurse. It is very usual that newborn seems to have trouble finding or staying on your nipple. Breastfeeding requires patience and lots of practice. Do not hesitate to ask a nurse to show you what to do, and request visits from a lactation consultant if you are in the hospital (many hospitals have them on staff). It is not at all advisable to give the supplements like lactogen. If she was sense less, the expressed mother milk by pumping was given to your baby. Your baby s mouth should cover a big part of the areola below the nipple, and your nipple should be far back in your baby s mouth. If latch-on hurts, break the suction (by inserting your little finger between your baby s gums and your breast) and try again. Once your baby latches on properly, she will do the rest. Exclusive breast feeding is very essential for first six months of life. Do not give any food, water or supplements for first six months. Hope this helps. Please write back for further queries. Wishing you good health.
