<s>[INST] i have a baby boy 3 years old. He is vomiting sometimes during his meals or sometimes after his nap during the day. He always refuse to take his full diet and when I forcefully want to feed him, he vomits by coughing. Please suggest what should i do. [/INST] Hello! Thank you for writing!Does your baby reise in weight?  There are some alternatives: you can give him much more than he can eat. Is this  caused by all kind of foods or only by one food? The best option is to visit your baby to a pediatrician gastroenterologyst. Wish you good health for your child. </s>
