This Little Kid is Driving Me CRAZY

Okay- it has been in the upper 90's for a couple of weeks now, and Seiler wants to dress for Antartica. He came into my room the other day fully dressed in jeans and a long sleeve tee shirt, AND a jacket. He was making me hot just looking at him. Last week I had to bribe him with a new toy if he would wear shorts to "preschool" everyday, for Fear that I would be labeled a horible mother; overdressing her kid for summer. What am I gonna do. He doesn't want to show his arms and legs for some reason. Even when we go to the pool. He wants to wait until we get there. What is going on?
