2) Having Your Character Pop Out Bazillions of Kids Is Not Interesting.
Now, playing a mature character with a child IS INTERESTING.
Popping out a child every time your plotline falters IS NOT INTERESTING.
Having one week pregnancies IS NOT INTERESTING.
Giving birth to a child then never ever referring to it again IS NOT INTERESTING.
Having your children grown and mature within two weeks of birth so they can have their own children which grow and mature within two weeks of birth, most especially if the original grandmother remains as buxom and sexy as your average 20 year old, IS VERY VERY NOT INTERESTING.

2 b) How to Make Having Kids Interesting
i. play out a proper pregnancy and decide in advance how long it should be- I mean, don't wait a whole nine months of real time, but perhaps three months would be good, so you can actually play out each trimester of pregnancy each month.
ii. RESEARCH. Read up on what pregnancy is really like so you can play it better. Also, know at which stage of pregnancy the kid is going to be a slight bump in your abdomen and which stage of pregnancy they are an immense thing that requires significan physical concessions.
iii. Have a father for your kid unless you have a really, really good excuse for spontaneous conception.
iv. Play your child after their birth. Consider including birth complications. PROBLEMS MAKE THINGS INTERESTING.
v. If you're playing your character as having an infant child, include some of the difficulties they run into- lack of sleep from all-night screaming, for example.
