As @HollyKnight says, it is different when they get to the teenage years, @ThatCleverFawn. You get a full night's sleep, and even a lie-in at the weekends, and can finish a cup of coffee while it is still hot! Yes, there are still difficult bits, and there were times when my dses were teens when I wasn't sure we would all make it to their 20s unscathed - but we did.
Apparently, during adolescence, the teenage brain is actually rewiring - changes are taking place in the structure - and while this happens, they can lose certain abilities - impulse control, temper control, sense of proportion and not seeing themselves as the centre of the universe, for example. The writer Charlie Taylor (author of Divas and Doorslammers) describes it as almost a form of temporary brain damage - but the key word is temporary, and it does settle down as the changes bed in, and these abilities return. The teen who was slamming doors and yelling at mum becomes, almost overnight, one who does his homework without being nagged, tidies his room voluntarily and gives mum an unsolicited hug - I nearly fainted!
And having boys, my house was full of their teenage friends - boys all taller than me, and all very sweet, polite and fun to be around.
