My youngest baby is sick, he has some stomach thing(from eating a pound of m&m's) The vet put him on E N Gastroenteric food that i am to feed him 2 tablespoons every couple of hours. But the poor thing won't eat it. I have tried to force it down but he will sip it back out. What else can I do to get him to eat? I already have to force water down him. Please help , he hasn't eaten anything in 3 days I need to get this food down him.
