Little Man's Annoying Habits

I cannot seem to keep Little Man's finger out of his nose! I have even caught him in the middle of the night with his finger up his nose and I could not get him to take it out. Along with the finger up his nose he also keeps putting his underwear on backwards and pulling them up as far as he can! He even puts his shorts on backwards. I have tried showing him how to do it correctly, but he wants to see the characters on his underwear. I don't really care that much though, as long as he dresses himself that is all that really matters to me!
