My son is 4 years old and not yet diagnosed.
His sleeping problems have been driving me insane for about 2 years now. As a baby I had trouble getting him to settle and he'd wake up frequently but I just put this down to being a baby. I somehow got it under control and improved it but just as he turned 2 it all went haywire again.
He goes through stages where he just fights his sleepiness and stays up all night. He has been known to stay up until 10am in the morning. He just wanders around the house, turning on the telly, playing with toys etc etc. Then he went into new stage where he would go to sleep, just not until late. He was staying awake until between say 12am and 4am.
His developmental paediatrician prescribed some pure melatonin to help put him to sleep which worked wonders. Within 15-30 minutes of taking it he would be asleep, my only problem now is that he is still waking up.
Some nights he just wakes up crying and I give him a cuddle and he is back to sleep until morning, other nights he wakes up absolutely hysterical and takes hours to calm down and go back to sleep. Due to his communicative problems he can't tell me whether he has had a nightmare or not or what the problem is so I'm very much in the dark. Often, when it takes him ages to settle down, I think he is too awake to go back to sleep and he is happy to ge tup and stay awake until the morning, even if it is hours away. He'll get up and put the tv on, or go into his toy room.
It is driving me completely mad, I haven't slept properly in so long. I'm finding it very hard to function, I think it's really impacting on my moods and it is virtually impossible for me to wake up in the morning. We have just recently increased his dosage of melatonin to 3mg and if this doesn't improve thigns in the next week we have another appointment with his Sleep Specialist. She may look into changing his diet.. which I don't see how it will be possible considering he eats an incredibly limited range of foods.
When will it ever end.
