My DS1 has just turned 2 and has been getting up at 5am for months. We've tried later bedtime, shorter nap, a bit of letting him cry it out, all to no avail. He isn't sleeping late enough, he gets tired and grumpy a couple of hours later, and isn't really cheerful until after his nap.
I've been reading rave reviews for the gro clock on Amazon and wondered if this is worth a try. He's only just 2, so am not sure if he'll "get it"
I'd really appreciate hearing about others' experiences with sleep trainer clocks, particularly with 2 year olds.
