No Sleep

I have NO idea what the deal is, but bumps will not sleep anymore. We put him down at the usual time and he is visably tired, but he will not sleep. It is 10:30 right now and he has been in there crying for over an hour. M says there is no getting him tonight because that is why he keeps crying. I am so aggravated because I want to know what is going on. Neither M or I can sleep because he is in there crying, but if we get him, all he wants to do is play and we are not playing that game. So now M is telling me to go into the back room with him so bumps thinks that we are asleep also. Hopefully it will work. . .
