Our four month old is excessively gassy. She has been fed in many different ways from breast to enfamil newborn to nutramagen to gentlease to and back to gentlease.She also has a problem with constipation and we give her one to two ounces of prune juice almost every day. Her gas and poop cries are pathetic sounding and we wish we knew what to do! The gas is constant and sometimes sounds forced, while other times it just comes out. We push her legs up sometimes to help with the gas. Please help! We hate to see hew so uncomfortable,
