I have a 4 year old who is a very picky eater. It is a chore to get him to eat anything other then pizza and fries. His pediatrician sais he is developing well and has no concerns. Hes always been small for his age. I want to make sure he is getting all the vitamins and nutrients he is lacking in his diet, but which kid drink should I use? Kid essentials or Pediasure?
