Your little one may not like try to sleep in a wet nappy expecially if he suffers from nappy rash. You will know if he has dirtied his nappy as you will smell it and it will “burn” his skin if left too. Have you tried puttting a pillow under the head of his mattress? He may feel uncomfortable or even nauseous when laying flat. Has he had a nightmare at some time when her was really scared for awhile. He may be having flash-backs of that. I did as a small child and still do with later dreams occasionally, often when I have only been asleep for a few minutes, sometimes nearer to normal wake up time.
