Slept too soon

Big guy was sleeping like a champ for 3 weeks. It was wonderful. Now I'm thinking we spoke or slept too soon. For the past week, he has decided to wake up every hour. Then during the day sleeping all day. Hence the lack of posts. I finally called the Dr, as I was concerned. She thought it had to do with his congestion (the kid is a snot factory) and gas (he's slowed down to once a week!). Then on saturday he finally had a huge poo! yay! Sunday he slept great. I was sure we were past it, then thursday night hit and he only slept until 1:30. I can get him to that time, then he's done. Not sure what the deal is... Hoping we can sleep again as I return to work on wednesday. Being sleepy at work wouldn't be fun at all.
