"Angel" by night now

When Paxton first came home from the NICU he would not sleep, for 2 weeks we fought for 1 hour of sleep. "Angel" by day and "beast" by night was his nickname. We can joke now but we both got anxiety when the sun started to go down. So we bought this expensive sleeper bed, thinking that maybe he could not sleep because he did not have the boundaries that the NICU box gave him. We recently started brain storming about what we can do now that he is about to grow out of "the box". He now takes after his mother and is a bed hog:) I realized this week that I do not need to stress over the little things because the boy will let me know what to do next...like move the box and let him sleep in his big boy bed. I will have you know after the purchase of the box we were finally able to get 3 hours of sleep at a time. My new dilema is how to get him to ignore the hungry stomach and sleep through the night.
