Ds is 6.5 months currently teething and lately won't have a nap at 4:30, he will lay in his bed up to 1 hour just wriggling around whinging , he isn't sleeping threw the night yet just one feed a night some nights I'm up 2-3 times just to put his dummy in , but my question is , he isn't sleeping long enough at his day sleeps though , he wakes at 6:30 so I try 9 or 9:20am for a nap but he only ever has one sleep cycle then by 12 he is tired. I've tried naps at 12 and at 1:00 but he only sleeps for 1-1.5 hours , so being awake from 2/2:30-6:30 is just to much for him and he is a mess !! What can I do ??
