DD gets cereal in the morning and a fruit or vegetable around dinner time. She has had about 10 different foods. This may be a silly question but I honestly don't know. It seems silly to call the ped about this. Can I/Should I feed her a fruit and vegetable at the same time at dinner? When introducing new foods we have do them from 5 days to a week. I haven't mixed anything yet. I make all of the purees myself. Our ped gave us a handout at our last appointment and we are feeding DD exactly what she wants us too, amount wise.
