One of my favorite parts of TS2 was getting pregnant and having kids.  It is exciting waiting to see what the baby would look like, and see him/her change over time.  So I love having kids.  It is hard for me to have only 1-3 kids in a family.

In TS2, the most kids that I ever had was 6-7 kids.  But that was with a good looking couple, and their kids turned out beautiful and different looking every time.  I usually stop after 3 or 4 for the same reason as you:  The parents would be getting old fast, and you won't know if they would survive throughout the kid's life if the adult had them later on in the stage.

But since I am able to control how long a stage is, yes, some families will have more kids.  But then some won't, because kids do sometimes require a lot of care, and can be stressful at times...with homework...I really hope they do their HW by themselves this game.

But this aging will change how many kids I have in some families.

But there are also traits.  So some may not want as many kids, or the kids pop out plain bad and crazy.  Then, I may lessen the kids.  But more kids for good trait families--especially family-orientated sims.  I wonder how would the computer control the sims that we aren't controlling?  Does it make sims give birth to an average amount of kids, like let's say most of the time, if you aren't controlling a family, the most they will have is 2-3, unless you make the parents try for a baby again.

Yeah.  YAs should be fertile.  Adults are now the middle age stage of life, and YA, they said their age is approx. 18-29...something like that.  So they should be fertile.  Imagine when University comes out, if it ever does.  Students can fool around too much in college, and will get pregnant...which is unforturnate, but that is different for TS3 though.

**TIP**

when one of your adult children moves out, have them take a teen sibling with them.. this leaves room in the main houshold for more babies to arrive !!

I'm going to have about 6 children myself, but I do not want to stress out my sims too much, especially if the children become a handful, you know with their unique personalities and what not.

At the same time not try to stress out the mother of the children, because since the child's personality could be altered due to the events of what the sim goes through.

the most i like to have is 3. i can't wait to see what childbirth is like.

but i'm going to make a female sim who dislikes children and never has any, since i always made my female sims have kids in the sims 2. she can just get married and live happily ever after lol

i agree with adam
i hate it when in TS2 for example you have a family with a teen and a toddler and the teen grows into an adult and moves out and lets say s/he has a kid and that kid grows into a teen and you don't play the original family not only is that kid(/teen) older then his oncle but the parent can have no relationship with his sibling

1-5... I'm not very good at keeping Sims alive, lol.
