Getting hurt before taking a nap

I’ve been taking care of my little toddy for his nap time (this afternoon). But it’s been three hours already that he’s just jumping, running, asking to be cuddled, and doing other annoying stuff which indicates that he hates to have a nap. Until he bumped his face on his bed and the reason of why he’s crying out so loud! But after that thing, he’s behaving and dozing himself to sleep. Whew! What a baby! He’s waiting that he will hurt himself first before having his nap. Ouch!
