Recently my 2.5 year old has started waking very early, between 4.30 and 5.30, screaming and shouting that he wants to get up. He will scream hysterically until one of us gets him up. His normal wake time is between 6.15 and 7am and he used to wake happy and would play quietly until his Gro Clock turned yellow, then he would call for us. But now he just screams hysterically and we can't understand much of what he's screaming other than he wants to get up.
He has a good routine, his bedtime is between 7 and 7.15pm and has been since he was a newborn. There are blackout blinds in his room and he has a little nightlight in the form of a Gro Clock which turns yellow when it's time to wake. He understands what it's about and how it works as we've been using it successfully for 8 months now.
Could it be that he's ready to drop or shorten his nap?
He naps for 1.5 to 2 hours, and is tired at naptime, often I will need to wake him otherwise he'd sleep longer. He goes to bed easily and happily at 7 with no problems at night.
I don't know if this is just a phase that we've got to stick it out and hope it passes, or is this a sign he needs to drop his nap?
