I noticed today when I took the runt out to check on it that it's tummy is still big, but kinda firm now on the kit's left side. Can milk harden in a baby's stomach? :? I've been pottying the kit one or two times a day, because I felt Mama probably wasn't doing it, with him staying so fat... What could be wrong with him? Is there a way to maybe to fix it? The kit's about a week old.
