Hello dear simmers!
Some months after I started playing the sims 2, I decided to search for baby clothes as I saw around the net some babies had it, so I went to moonlightdragon.freeforums.org because I remembered that I had seen them there before, and I tried to install Chris' Hack Mod to buy baby clothes, having like this a lot of cloth options at the same time, but actually it didn't work for me, as my sims would often get error and they couldn't even go to school or work. So I unistalled the mod, and installed some cute default clothes (I also found out how they work, yay!).
Go here for default baby clothes for your game: http://moonlightdragon.freeforums.org/default-outfits-f128.html and here for non default clothes that use Chris Hack Mod (download mod here:http://moonlightdragon.freeforums.org/chris-hatch-s-mod-t1306.html):http://moonlightdragon.freeforums.org/non-default-outfits-f129.html.
YOU MAY HAVE TO REGISTER ON THE FORUM TO DOWNLOAD STUFF BUT IT'S TOTALLY FREE!
Basically (for default baby clothes) there is a unisex outfit, and another for girls only (Gonly it says on it's name while the unisex is named normally). You can only have one of each, if you install more than one your game may get confused (read the info about it onhttp://moonlightdragon.freeforums.org/important-read-before-downloading-complete-user-manual-t56.html if you wanna know better how it works). You put it on the downloads folder and voila! You are done! If you wish to change the outfits, you must quit the game, replace the files with the ones you wanna, and start again your game :)
Happy Simming! :D
