One Step Forward

Then two steps back... I was so excited because for the last several days daniel has been sleeping at night (although only for 1 - 1 1/2 hrs at a time) in the co-sleeper. Then two days ago he started napping for 1 hr in it also. YAHOO. Then last night something happened and he was miserable all night. We literally didn't sleep. He didn't want to eat but he was hungry. He was tired but wouldn't sleep. It was very frustrating And now we are very tired.
