My son is 6 months, and is not keeping solids or milk down. We know he has some form of allergy, tried that special prescription milk, which hasn't helped. The pediatric dietitian is seeing him on the 27th of June (her 'earliest' appointment) he's not been keeping all his food down but lately he's just not keeping ANYTHING down at all, he's not dehydrated but he is grouchy and hungry, but i don't know what i can give him! The health visitor isn't on duty till Tuesday, help please? 1 very worried 17 year old mother!
