So the pediatrician now suggests ready to feed formula for the first 2 months over powder. It wasnt like that with my daughter and she's only 2 and a half. Does anyone know why they suggest that? He upped his ounces again and it's so hard to keep up with making sure I have enough and running to the store every few days for more. I'm going to bring it up at his next appointment to see if I can switch to powder but until then I wss wondering if anyone else's pediatrician said this and why they would??
