So. I nursed Hannah until she was almost 2 years old which gave me all sorts of (false?) confidence. But then with Michael we only made it four months before he wanted nothing to do with it, and we started on formula and bottles. I've never used any sort of milk boosting anything before, and Chris thinks that I'm being paranoid, but it can't hurt, right? Has anyone used anything like this and had much success or hated them? I'm all ears.
