36-40 weeks.
I want to know how long it takes for a baby that was born from two married mii's to be full grown and ready to move out. It's been three days, and my homestuck mii's John and Jade had their baby Josephine and she is stILL JUSt a LITTle bABY,, so... It takes approx. 36-40 weeks for the baby to be fully developed. Before that, the baby is premature and might have to spend some time in an incubator. Amount of time spent dep … ends on how early the baby is born. Report Abuse. Each baby is different, even each toothe is different, my baby's top teeth took a couple of months for the tooth to come out fully, and the bottom ones took a few weeks. My eldest daughters teeth only used to take a couple of days.

First 3 days is when they're infants, then toddlers, and then the last few days are young child. It really just depends on chance. So in short, about a week at most.
