S.L.
Yeah, so much for breastfed babies "hardly ever getting constipated!" My son always had painful bowel movements, the consistency of peanut butter. His ped advised 2-4 ounces of juice. Water works, as does juice. I always diluted his regular from-concentrate juice half and half, but now I do even more. It's 1/3 juice to 2/3 water. Saves a lot on juice and calories! I gave it to him in a bottle every day, and he only had problems when we forgot.
Anyway, that helped a lot.
He was also very gassy, and I spent many a night awake with him laying on my chest on his tummy. That's the only position he liked. Then I got simethicone. I bought the WalMart generic Infant Gas Relief Drops, which is the same as Mylicon. It TOTALLY works. We took it everywhere with us, and he liked it so much, we called it "gas candy." It saved my sanity.
