This boy of mine

I am in the middle of potty training him which is going well except for his stubborn personality. He likes to cry and tell me no every time I ask him to sit on the potty. He definitely knows what he is doing but I can tell he likes to be difficult. I am trying to figure out ways to trick him so he thinks it is up to him. Also he is fighting his naps which is fine by me if he gives it up. But he will sit in his room and fall asleep super late in the day somewhere and then won't wake up no matter how hard I try. Which in turn makes him stay up until 10 or 11 at night when I just want to sleep!!! Man I love this boy--but these past few days have put me a little on edge!
