I recently bought Millennium Boys and Girls. LOTS of stuff for the girls at the various MPs and free sites, including a lot of sexy stuff totally inappropriate for little girls, but hardly anything at all for the boys. It's sort of amazing, and a bit disappointing. Off the top of my head the best items I've seen for them are the default clothing pack at DAZ and the PT bodysuit at PoserPros, although again, that leaves the PS boy out of the picture. Hopefully the next-generation Millennium boys will be better supported.
