How can I comfort my boyfriend ?

My boyfriend woke up this morning not feeling well. He keeps farting which by the way is not funny. He said his belly hurts he and his friends did eat a lot of chocolate yesterday. We just got up to watch my cousin get on the bus for his first day of school then we went back to bed. He's moaning really loud he's complaining his belly hurts he's starting to cry a little. How can I comfort him ?
