You Should Have One Kid
Having a child is something you'd like to experience, but you're not sure about a crew of kids.
While there are downsides to having an only child, you would be able to devote all your resources to him or her.
You want to be able to balance a family with your other goals, and that would be hard to do with a lot of kids.
One kid is totally manageable for you. It may be a bit stressful to have a child, but it would be totally worth it!
