Girls, the child had strong vomiting in the morning when feeding lying down, then after some time fed on hands, also vomited quite a bit. Then gave porridge little by little, and held out all day without vomiting. At 12 at night fed a little breast milk, then when feeding porridge again vomited in large quantities. There is no temperature or diarrhea. Could this be due to allergies, I'm afraid it's not good (who has encountered such)? The doctor was, said cerucal to give and nutrilon reflux.
