Around eight Sim days.
I believe the children do grow up I just don't know when !
Six in total, it take 3 days for a baby to become a toddler and 3 days for a toddler to become a child.
They dont
About 3days depending if u adopted it or wohooed it
Only the baby can grow up. Which is 3 days. The boy or girl Sim(child sim) can't grow up.
Not very long about 2 days if you play it a lot
they dont kinda stupid huh
It takes about a week (in sim time)
if you talking about the sims on pc, then it tells you how long it takes at the bottom of the page, underneath the picture of you persons face. different sims have different life spands.
It shouldn't take very long. On mine the time flew! :) LMK
They will grow up from babies to children but do not grow up into an adult unless your hero sim dies then you can choose for their child to grow up and take their place in that profession
about 3 sim days i think
