DS1 is 3.3 and fell asleep in the car at 12.30 on the way back from playgroup. He won't go to sleep until after 9 now and this is why he is tired today as the same happened yesterday - he had a nap at nursery and then went to sleep late but still woke up at 7am. A vicious circle. I tried to wake him up at 12.30 and he cried "I want to be sleeping" so he still is, as is his 22 mth old brother - peace for me and I'm 11 weeks pregnant so I like the sit down. Should I wake him or leave him until 1.30 now? I feel a bit guilty to leave him asleep.
