Re: Missing Sim - Is in family tree

I hate to suggest this, but...

If you went to visit the household when you weren't playing them, Sims sometimes don't take care of their kids when you're not playing them and if you're on the lot sometimes they get taken away. I always always always care for any babies on lot and give toddlers food if I have it.

Do you have any mods in your game? If you have MCCC you can summon the toddler by clicking on the mailbox and choosing MCCC...
