For those whose have toddlers that eat but dont gain or dont like to eat... have you gave them pediasure? Is it effective in helping child gain? Is it worth the price. My son is going to be 2 in 2 1/2 more months and has been the same weight since he turned one. He has stayed 25 pounds from 12 months to 21 months. Idk if it's because he started walking at 12 months so hes more active now or what but I dont want people thinking I'm neglecting him being hes not gaining.
