Coud be, Carson had to leave school a few weeks ago as he began throwing up- he made it out of music class in time, poor kid! I know our peds nurse has always told me if hte fever leaves & comes back, they need to be seen as there may be something Going
on. My kids were always problem children when they got sick, so they pretty much make me bring them in anytime I have to call. Hope your little one feels better soon, not a fun way to spend early summer.
