What gives?!?

So if you have read my blog before or are a good friend, you have probably heard my struggles with getting Grey to sleep in his own bed. As I continued to get bigger and bigger, our bed was getting smaller and smaller and the need to get him out was very pressing. So we agonized for a few weeks and I read everything I could about getting your toddler to sleep in his bed through the night. And all of a sudden, we started doing pretty well. He still wakes a couple times in the night, but just needs a binkie and a love then lays himself right back down. Well, tonight it is 11:41- way past my bedtime- and I am down on the computer while he is crying in his bed. I have been in there 3 times already and he won't stay calmed down. He does okay for a few minutes and then starts crying again. What gives?!? Hopefully this is just a one night thing and that he gets with the program again. We don't need to go back to square one!
