I have a friend that had her first child around the same age as your wife, and she asked the doctor to have her tubes tied when she gave birth. She knew for sure that she didn't want to have any more children, but the doctor tried to talk her out of it because of her young age. The reasoning was that she might reconsider later that she did want another child, so he was reluctant to perform the procedure but he did when she insisted that she was sure of her decision.
