My daughter is just over 8 months old, we're lucky if she only gets up 3-4 times a night (she has to wake up at least once for food and medicine as she has a haemangioma over her left eye, before this she would sleep right through) and has done from about 2 months old.
She's been rolling from 4 months and crawling from 5, naps twice a day usually for 30 minutes or so. Despite this my wife and I still try to go out once or twice a month together without Sophie, which I think is a priority over individual hobbies as it's too easy to just get stuck in a routine and forget that you were a couple before you were a family.
