I too went though this with my son. Yes there is a generic brand...I know meijer carries it & I also think marsh & kroger do as well. My sons ped also suggested carnation breakfast in addition to the pediasure ...it is packed with calories. Try to give your child high calorie foods as well...this will hopefully increase her weight. But do not worry too much. Some kiddos just take a while to start their growth spurts. My son is 31/2 now and weighs only 29 lbs. He is healthy but just doesn't grow that much. If he hasn't made big growth jump at his 4 year appt then we have to see specialist. So don't think this is anything bc of you...its just how some kiddos are! :). By chance was your little one a preemie? My son was & that is the main cause of his lack of growth. But just keep in mind there is help out there...
Good luck!
