My 18 mo old is very regimented has always been. He thrives with routine. So today we were out at lunch time I fed him in car and tried to put him right into crib wheh we got home. His usual routine is lunch at 12 and straight to bed for a nap at 12:30 but today since we were out he had some lunch in the car and went down for a nap at one but he never fell asleep should be due early bedtime how early?
