Dry apple jacks and gatorade

Yesterday went well until we got home at about 7pm. James' mom was here and she bought a mocha cake. My first clue that something was wrong should have been when JJ only wanted a couple of bites and then said he was full. Within about 5 minutes he was crying, holding his belly and saying it hurt. I told him to get a bowl and within a minute everything in his belly was out of his belly. I cleaned him up, gave him meds and put him to bed. About 1230am he woke me up with it coming out the other end. This morning he said he is still feeling bad, yet he wanted to eat and sounds fine. I gave him dry apple jacks and gatorade.
