My daughter had colic from the moment she was born, and it got so bad as time went on that we actually had to give her liquid zantac twice a day in order to control it. In tandem with the zantac, we switched to soy formula and we used mylicon drops as needed (they work GREAT!). Her colic and constant spitting up went away overnight - the soy formula is still fortified with all the same vitamins and minerals as milk based formula, but is much less difficult for babies tummies to digest which cuts down on the colic a ton.Infants have a hard time digesting the complex proteins in milk based formula whereas soy has much simpler proteins that the babies digestive system doesn't have to work as hard. Mylicon drops are a godsend for many parents, and when you feel that her tummy is all bubbly and she is unhappy, give them to her. They are super safe.
Follow your doctors orders and your babies colic will go away!
