My daughter had to have a C-section to deliver number 2 child as she had one for number one. Her little girl who was 6 when the number 2 was born knew mom had surgery to have the baby. Some time later she asked her mom if there was a way to keep from having babies because she was not ever getting cut open.
This same little girl who is 8 now came home from School last year and told her mom that if either she or her brother had to be kidnapped she thought it should be her because they had had her longer than him.
