What happened to my sleeper?

Our little Daniel does not sleep in anymore! He used to sleep from 7/7:30pm to 7/7:30am (on the weekends). Well his routine of waking up at 5:30/6:00am on the weekdays has rolled into the weekends. So every weekend morning, we hear the "thud" as he jumps down from the top stair of his loft bed. Then he quietly walks in our room and says, "good morning!" Both Jay and I quietly respond and let him crawl into bed with us in hopes that he'll snuggle up and fall back asleep. I don't know why we think this method will still work, because Daniel is WIDE awake. He'll crawl in, but continually talk about random things. This morning it was, "Well, what are we going to do today, guys?" then "Dad, you are blowing air in my eye!" (aka nostil air - LOL) and then finally the usual question, "Can I watch a movie?" By this time we are awake enough to go out to the living room and put on whatever movie Daniel wants to watch so we can catch at least another hour of sleep. Most of the time we are not successful, but just toss and turn, and finally give up and start our day. The upside about waking up by 6am on the weekends, is that it sure makes for nice long days! At the same time, it's also preparing us for the "true" lack of sleep that will be here before we know it!
