My wife and I want a baby but we have a problem. What should we do?
I recommend talking to a talking a fertility doctor to determine your chances of getting pregnant. If there is a medical problem then, you can consider adopting a baby from one the adoption organizations in your area.
You already have a daughter-what is the problem? Do you want another child and have somehow become infertile?
You need to go to a fertility clinic so you both can get checked.
