Jackson spends a lot of time hanging off of Clayton's tray. And Clayton spends a lot of time doing his best to ignore him!
Clayton is really pretty much used to Jackson, but he is still not used to someone being in his personal space ALL. THE. TIME. He gets really worried and bothered with Jackson climbing all over him and his stuff--but he's doing the best he can to get acclimated to having a little brother hanging around. :)
