My Son is 5 months old and since he was 3 months he has been dealing with gerd so his doctor says. he will throw up after meals sometimes right after sometimes 2 hours later. we started boiling whole milk and removing the film off the top and giving him that and he stopped throwing up instantly. we tried Enfamil gentle ease formula and regular similac and he throws up any formula he tries ? is it ok to be giving him boiled whole milk and polyvicol vitamin drops in his bottle ?
