Surprisingly, not that much. Maybe a little bit more planning, but having only one kid, it hasn't been that much of a hassle. Maybe the first 2 years before potty-training were bit more difficult, but now, closing in on 5 years of age, it's pretty much the same as before. We do a bit more activities that he likes, but even museums, expositions and other adult stuff, he has to put up with it if we as parents decide it is something we want to do. We're drinking less alcohol than before, too, but that's not necessarily because of the kid.
