Intersting that a doctor would recommend giving juice to a child under 1 when it is not recommended until at least age 2 and prefereably much later. Maybe he just assumed you were giving her juice.

From the other replies, it seems that you could either keep giving her the normal formula, or try a lactose free one. As to which way to go, well I would say trust your intsinct. As a Mum you do know what the right thing to do is, you just have to trust your instinct. Whatever you do will be the right thing.

I hope she gets better soon for you.
