Yep! Chris Hatch has a mod out now that lets babies have different outfits. I just made a mess of gowns and diapers and have fired up my game to see what I can do with them. (7 gigs of content does not load quickly but I need to look at my buy and build stuff and see if there's anything I can purge, anyway.) But so far, it looks like they can be treated just like any other body mesh-- the age has to be set for babies in SimPE, but that's easy enough. The big challenge is recoloring blind in Body Shop.
I look forward to seeing how things work out! Like, a lot! (Seriously I've made sixteen diapers, eighty-three baby gowns, and the same gowns with coifs (lilyturtle did some mesh combining for me), and I have plans for short smocks with and without booties, too. Color actions mean that babies are quickly going to have more clothes than toddlers, if I don't get on with my toddler-clothes plans.)
