Our 4 yo has had sporadic(1-2 times per day) episodes of vomiting over a 3 day period. I normally would not be concerned, but the pattern seems weird. Her episodes are in the morning and before bed. She has not eaten much over the last 3 days and the only true stomach contents vomit was on day 1. Another cause for my concern is this is the second time this month she has dealt with this. One last key to this mystery is that this is the first real illness she has had in her 4 years. Concern?
