The matchmaker usually comes from age 6-8. She comes at certain times. I know two of the times are 3pm and 6pm. When she arrives, it will appear as an old woman, hair in bun, scuttling in sideways with a book. Use the c button to catch her before she goes away. Then she will bring a mate and ask love? Click the b button on yes to acceot and soon a little one will be on its way. If your tama has turned into an oldie, then it is too late for the matchmaker, but you can still get a child through connection to another tama. If it is still an adult, I recomment changing the time to one minute before 3 or 6. Sometimes several tries are needed before you can catch her. Good luck.
