No training manual included

No license is required to have kids. From riding in a car seat to driving the car, our children are with us for the rest of our lives. Babies grow into toddlers into pre-schoolers into children into tweens into teens into young adults into full-grown men and women. You must be willing to ride it all the way through.

You can't exchange them or return them for a refund. (The current average cost for raising a child until she's 18 is around a quarter million dollars.) You might want to try but it ain't happening!

Before you have children, understand that this is life-changing commitment.
