I out him to sleep for a nap along with me and my son and he woke up and pulled his blanket off him and flipped him over in his crib....how do I stop this?

he is 2 nr don't really understand..

explain to him that you appreciate him wanting to help, but that he has to grow bigger in order to help in the way that he wants to and In the meantime give him tasks that he can actually do so that he feels like he's still "helping" and apart of everything,know what I mean? that's awesome that he wants to help so much
