My son (11 months old) has one nap a day and he'll go down for 2-2.5 hours, sometimes 3. This works fine for us and he goes to bed at 8pm. But if I'm out - like today - I didn't get to put him down for his nap until 3.30pm (he usually has his nap any time between 1.30pm and 2.30pm). We were round a friend's house today and other babies were there so I knew he wouldn't sleep there and he was full of life until we left and I put him in the car. Within seconds, he was asleep. We were home within 15 minutes where I put him into his cot and he went back to sleep but he then woke up screaming about an hour later. I know this isn't enough sleep for him. He needs 2 hours at the very least. So I went up and he was wide awake crying. I changed his nappy as I didn't get a chance to do this when we got in as he was asleep then I gave him a cuddle and put him back in his cot. He was crying throughout all of this. I then stroked his head and shushed him but it didn't help so I just left the room for a couple of minutes and he soon stopped. But this doesn't always work. Sometimes he is literally inconsolable. I end up bringing him downstairs for a bit but he'll still be crying, then I take him back up to his cot and he'll eventually settle back down again. Any advice on how to deal with this? I'm pretty sure that he's waking up crying because he is overtired by the time I've put him down for his nap. But he just doesn't want to nap when he is anywhere other than his cot or in the car.
