When do they start to like sleeping?

My son is only 4, and although he falls asleep easily and sleeps well all night, he doesn't *love* sleep or decide on his own to go to bed, ever.

I remember loving to sleep as a teenager (I still do!), but I can't really remember how old I was when that changed. So I'm just wondering, for those of you who have older kids and have seen this transition, when do they start liking to sleep, and how does the transition happen?

Just being nosy and curious.

My oldest is 10 & she's been doing the "just 1 more minute" thing for at least a year.

However she likes to stay up late.
