Lit, I'm sometimes also faced with the same problem as I live in a one bedroom apt with my girlfriend and when she sleeps or has bad headaches I've gotta use headphones. Oddly enough, if I talk semi-low it won't disturb "the witch", but only after she's really zonked out. Congratulations on your growing family. I've vied against kids myself, instead filling the void with two dogs (which are like perpetual toddlers without daycare or college loans) ;-)
