Hi, I have a 3 week old baby. He is on mixed feed as he is unable to latch properly. He doesnt get his tongue out for breast feeding and ends up biting for extracting milk which is resulting in sore and cracked nipples and red areola, where as for bottle he uses upper jaw and the tongue. How can I make him latch properly and train him to get his tongue outside?? I have smaller breasts and nipples incase that helps in giving instructions..
