my 8 week old son is bottle fed, half breast milk and half formula, for the past 4 weeks, due to low supply. he has had lots of gassy belly issues since he was born. With the help of anti colic bottles and mylicon drops, he is MUCH better. but the past few weeks, he has tons of terrible smelling gas. My question is, should i try a non dairy formula instead of milk based? he is on Enfamil Premium Lipil. I was contemplating trying Similac Isomil, for fussiness and gas. Or maybe I should try enfamil gentlease? Anyone have any ideas? His ped said that there wasnt a good reason to change unless he had more problems, but it seems to me, it might be worth it.
