S.T.
Think of a time when you did not feel so hot. Food sometimes can be put off if not feeling well. If he was vomitting he made still have some nausea. The antibiotics for the ear infection do cause nausea and if he has that he may not know how to describe that feeling to you. So instead he does not eat because he has the nausea. I would just keep an eye on him. It is most important that in this hot weather he continues to drink fluids. Good luck, he will be back to normal soon. www.livegreeneasy.com
