Babies were so cute TS2. They weren't burrito babies. They could be 'bathed in the sink', passed to another Sim, or the Sim could interact with the baby while it was being held. They had the bouncer, and they had the activity play mat. And of course the other things like changing table. And TS3 had the swing from the Store you could put the babies in, which I loved.
Edit: OMG I forgot the strollers and playpen from TS3. They need to free the babies and we need all of this stuff back.
