My just turned 1 DS keeps waking 40 minutes after start of his nap (both for his morning and afternoon nap). He wakes distressed and has a bit of a 'meltdown', where he is just so tired.
I have tried leaving him to get back to sleep, which he sometimes does, but some times he just works himself into an overtired crying frenzy, so I get him up. He then is ratty and irritable until his next nap. He sleeps really well at night, 12 hours.
Any tips or ideas please?
