I got my hopes up when I read this thread. My baby who just turned one has the same problem. He wakes at 4:30am every morning. If I put him to bed later, he still gets up at the same time. If he's a real grouch and has to be put to bed earlier in the evening, he gets up at 4am. I think it is something that they just have to grow out of (I've heard once they start school you can't get them out of bed), but I'll be keeping an eye on this thead to see if anyone has any ideas.
