My baby just turned 6 months old and I am worried to the core. I started him on rice powder and he can only take 3-4 baby spoons of that cereal. He can tolerate very little yolk and if I give him 1/4th of yolk he will projectile vomit for a day. Same goes true for anything that is fed to him that is more than 4 baby spoons. I am troubled that his tummy is just too sensitive as other babies of his age are eating larger volumes of purees etc without any trouble. Please can someone offer insight as to how much he must be eating in day???He is a breastfed baby.
