What do you think is the main reason a toddler wakes early? I'm talking 4:45/5 am and thinks it's time to start the day, or hysterical at 5:15 and obviously needs more sleep, but it takes FOREVER to get him back down? I feel like we've tried everything with our 17 month old and I'm just exhausted from this...we are in the midst of the 2-1 nap transition, and some days he is up SO early, I try for 2 naps, but then he refuses to take a second one, so then he's been awake for 7 hours. Ugh! Could he be overtired??
