As long as I can remember DS has been an early waker (5/5:30am). He is now almost 12 months old and he still hasn't outgrown what I had hoped was "just a phase". He is a "spirited" child who wakes up raring to go. To be fair, he goes to bed at 7pm and sleeps through the night, but lately, I'm starting to wonder if I should leave him in his cot when he wakes at that hour. The reason is because yesterday, out of the blue, he slept in until 6am and he was a different baby. He wasn't clingy, yawning and rubbing his eyes by 7am. I'm now convinced that he wakes us before he's finished his night sleep and I've been perpetuating this for a long time. He ends up having to have his nap by 8/8:30am because he's exhausted by then. I need advice because when I do try to leave him in his cot, he becomes hysterical after 30 minutes - no one gets anymore sleep and it's a miserable way to start one's day. But maybe I really need to dig in my heels and be firm that he won't be allowed to get out of bed before nighttime is done (ie before 6am). Do people think this is even an effective intervention at this age? Is there any other way out of this?
