My 2 year old woke up day befroe yesterday and was sick 7 times during the course of the morning, bringing up all fluids. Took him to docs at 12 and doc said nothing to worry about no temp or anything. He booked up and was full of beans for the afternoon and kept fluids down. Came to bath him and had a pin prick type red rash on his body not arms or legs. Has been fine but rash looks like spread to legs and arms and kneck. Has one red spot on his side, do you think it could be chicken pox?
