Ah... my 18 year old (PG) did not sleep through the night until she was 5. I think of it as just another of her sensitivities (noise, food, etc.). She did go to sleep reasonably well. ANd when she got up she didn't stay up, just "needed company" at about 1 or 2 am every night. So we played musical beds and went back to sleep with one of us cuddled with her someplace. When she was 5 we moved out of the city to a house in a pretty rural, quiet area. And got her a bigger bed (double) -- figured if we were going to be laying down to get her back to sleep we might as well all be comfy! A few weeks after moving she started sleeping better.
She was not a cuddly, social kid at all when she was awake. So we figured that if this was the time when she wanted to be close to us, we could deal with it for a few years as long as everyone got a reasonable amount of sleep.
