Hello! Tell me how your little ones eat their baby food? Our pediatrician prescribed exact portions that the child should eat and then replace breastfeeding. Well, honestly speaking, my daughter eats on her mood, sometimes she eats, sometimes she refuses, sometimes she eats half of it. How can I get to this replacement of breastfeeding? Maybe there are some tips?
