Well Dad,
You do have to aware of the "little one" ears, so playing your floorstanders at Metallica levels in your living room is probably going to be a "no no" for awhile, and over doing the bass can be upsetting for an infant trying to sleep. But playing your music at moderate levels shouldn't be a problem, especially if the music is somewhat mellow. Playing music with female vocals, classic jazz, acoustic music, string quartets and piano music and the like is actually a good thing for babies and young listeners to be exposed to. Actually I was reading an article the other day that talked about unborn babies being able to hear and respond to sounds quite well at 6 months into their development.
