Pregnant sims 3

[Cassie]

Well I'm going to try and make all different sized Sims to make it more realistic. However I've said this before but I do have this obsession with beautiful Sims. But I'll definately make at least one obese Sim, to try it out. I don't want to appear unsensitive about this I'm just curious is all. Becase well, that's how it is. You can't tell when a really fat person is pregnant looks-wise, so I just want to know how they're working on that. It would be nice I guess, if there was an option where they could WooHoo and get pregnant without us knowing, and then if it was an obese Sim and we couldn't see she was pregnant, she'd just pop out a baby or 2 (or three!) and we'd be like, "What the HECK?!".
