General

I need quotbabysittingquot help.

So, I was sorta left in charge of my 4 y/o cousin... I left him to nap, but he decided not to sleep. So then, I told him," If you don't wanna go to sleep, I won't let you play the wii." and he didn't go to sleep. and then, after he wakes up, he immediately wants to go play the wii, and starts crying to my grandparents when I don't allow him to. Then he starts hitting me... -_- I didn't really want to enforce a very strict parenting-type thing, so I just let him play the wii, but I'm afraid if he just gets his way in life he'll end up worse than I am/was...(I remember being pretty spoiled, but not worse than he is)

... so anyways, I told him that after 30 minutes, he would have to go play the piano, and all he does is ignore me.
Basil, what the do i do? I'm kinda frustrated... ._.;
