Thank you so much for responding so quickly. Being a first time Mom, I have been following the Ped's advice to the letter. But when she told me not to add the third meal until after 9months of age, I really questioned her. The Ped's believe is that my daughter will make up the calories in formula. My daughter is just shy of 20lbs, and very active. Anyways, as I said she is much happier now, so that makes me happy. I will experiment with additional solids and see what happens.
Thanks again.
