I'm going out of town tomorrow and I have to get up really stupidly early, so I'm just going to copy and paste the directions from the post for you, I'm sorry I can't be more in-depth.
0. Purchase the Buy Baby Outfit teddy bear. There is to my knowledge no other way to buy baby clothes. Yet? Maybe 'yet.' 1. Have your parent Sim either hold their baby or put their baby on the floor. I haven't checked this with every possible combination of relatives, but an unrelated adult CANNOT get new clothes for a baby. Didn't think to check with teenagers. Somebody try it and report back? 2. With your parent Sim selected, click on the teddy bear and select "Buy Outfit For..." which should lead you to the names of all infants ant toddlers in the household. Click on a toddler's name. 3. A standard clothing-purchase window will pop up. DO NOT CLICK ANY AGE ICONS. Click on one of the gender icons instead. That's the only way to get to the baby clothes. Select and purchase baby clothes as you would normal clothes; they only cost $25 each so stock up. Hit the check-mark to buy clothes. 4. When the clothing purchase window closes, a plan outfit window will appear. So... plan your outfit. 5. If you forgot to plan your outfit, panicked and hit Close, or just want to change your baby's casual clothing for the season, buy one of the Maxis changing tables and have a parent Sim Plan Outfit For their baby as they would for a toddler.
