It gets better after a few years mate, I generally have a few hours at night now to spend time with the missus, game/watch movies, do writing/side projects. This is with a 3.5 and 2 year old.
For what it's worth I don't regret it but man, I really do think "hmm... when will I next have 15 minutes where I have the use of both hands and no creature yelling at me and I'm not at work?"
I could just sleep less (with dire consequences noted here), but I've managed to keep getting 7 hours or so a day (not all in one go, but it could be worse).
