They will let you know how much they need!! If they do not cry for more let them be. I had the same questions and that was what everyone told me. A Baby will not eat more than what they need. My daughter 7 months old eats 3 tbl spoons rice in am, One fruit for lunch and one veg for dinner. We normaly use 3-4 7oz bottles each day. From 7a until 8pm
