Back from the paed, and she wants me to keep with the hypoallergenic formula that has the lactose in it. She said she does think that it is either him getting used to the lactose, which he's not had since he was 16 weeks old, and a general getting used to new formula that is doing it.
AND, he's had FOUR whole solid poops in the past 3 days! A few runny watery ones, too, but four is four more than he'd had earlier this month!!!!
I also bit the bullet this morning and gave him a sippy cup with cow's milk in it. Never going to know until I try. He hated it, as he does anything new, but drank about an ounce over an hour and not a problem yet! Fingers crossed that maybe all of this is an irrelevant thread and I can just get him onto MILK!!!!!
