On the other hand, with 2-3 children (or more), unless all your children have the same extracurricular activities, you'll spend a lot of time driving/accompanying them to their various activities. Depending on the children, there can also be a lot of fighting going on, which can be tiring for the parents. I'd say the jury is still out on the question of the optimal number of children (including zero).
