Well, you can't. The limit is one. Now do you understand? And anyway, having two babies
would be way to hard. I have one and it is already hard. It really ruins your "social
life" and you can't stay at other places with your best friends that much as you have to
go back home and take care of the baby/toddler. And if you woo hoo, it is more likely you
would die, if you have a toddler or babes. See? Hoped it helped.

This is just on the top of my head, but... You could try to adopt a baby it may or may not
work but at least ur sim dosn't have to die and your baby or toddler dosen't ruin your
social life whenever you leave the nanny comes and takes care of your baby for free so you
could go wherever you wana and the nanny will allwys be their but you can't socialise with
her for a randome reason :)
