Lately, for about the past month, LO is 9 months old and has been waking insanely early. He goes to bed around 7:30pm each night, but has been waking consistently between 4:30am and 5:30am (that's sleeping in for us). It's crazy! The sun is not even up yet! I've tried changing his bedtime in case it was too early, but then he just wakes that early and is grumpy because he got less sleep.

Help! What are your tips for early risers? If I could just get him to stay asleep until 6 or 6:30, I would be SO happy!
