Today my 19 month old woke up acting normal. He ate breakfast and I took him to the baby sitters. When we got there , he vomited which I thought nothing of because he has gotten car sick before. He ate again and immediately after eating, the sitter picked him up and he went limp. His eyes rolled back into his head, and he would not hold his head up. He vomitted two more times and remained listhless. After taking him to urgent care, the urine culture and strep test was negative. They put him on Augmentin and stated that they believe he has strep but it is in the early stages and there for did not show up on the strep test. I am gravely concerned, as he just ate again and is having the same reaction. Please help
