Big, um, helper?

Karah has been fighting a case of the sore bum along with her ear infection, so I've been letting her air out during diaper changes. During one of these times, I turned around to grab a clean diaper when Jay comes running in with a new diaper, a handful of wipes, and tackles Karah, screaming "I do it! I help! I do it!!" Oh boy! Luckily Karah is used to this kind of treatment (poor girl) and played along nicely. I told Jayden that he was a very helpful little boy, and he reminded me that he isn't little, that he is a "Bee boy." I nodded and went to throw away the diaper. I came back (literally 5 seconds later) to find him completely naked, wiping himself, and standing over a dirty diaper with a huge smile on his face. "See? Bee boy, Mommy!" Sighing with relief that it was only wet, I helped him put on the clean diaper...I only had to make sure it was facing the right direction! He can do all this, and he refuses to sit on the toilet!!! There is a very big question mark in my head about this....
