I'm 36, no kids, yet, and still like to "party" most weekends. My partner and I are quite lucky in that we have a decent amount of friends and family we see regularly. Half of them with kids, half not. Most of the parents do not get to party much since they've had the kids but one couple, we'll call them Alice and Bob, haven't let their child affect their partying at all really. Regular house parties and gigs, late nights, loud music at home and the kid just sleeps through it. Having a couple of good baby sitters and frankly bringing the child up knowing all their friends and joining in has made it very easy for them. I hope if/when we do have kids of our own, we'll be like Alice and Bob.
