This part can be very annoying. It takes the baby three days to grow into a
child. That seems like nothing but if, when the baby is crying, isn't taking
care of immediately, social services will come and take it away. They do give
you a few chances, first there is a phone call, then they come and take it
away. So you have to be very aware. There are three interactions that you can
do with the baby, Sing, Feed, and Play. Since it is impossible to determine
which one of these interactions the baby needs when he is crying, I would
suggest just selecting one and then queuing up the other two.
You don't have to leave the crib where it is, move it somewhere that you will
be able to get at very easily. To move it, just go into buy mode and select
it, then move it where you like. Make sure to keep at least one sim awake at
all times. Have one sleeping while the other is awake. I would suggest buying
a cappuccino machine to help the sim stay awake.
Do this for the next three days and always make sure to get to the baby as fast
as you can. Put a recliner in the room with the baby and right after the baby
is done crying, take a nap. Your sim wakes up pretty quickly when they are
taking a nap, unlike they do when they are in bed. So this way when the baby
starts crying, your sim will wake up and be able to care for the baby as quick
as possible. When the three days are over your baby will grow into a child.
If you want to get rid of the child, you can send him to school, once he/she
gets home make them study on the computer. Do this until they have A+ as their
grade, then send them off to prep school. *Bust Out mode only!*
It is a little different in bust out mode, you can only have a baby in a house
where it has the objective "Have a child." A child is required to finish the
game completely so you must have one.
