What version is it? The matchmaker will come 3 years after the Adult. She will come anytime but the most common times are 10:30 AM, 3:00 PM, AND 7:00 PM. (Set the time a minute early).
However it you keep on refusing the matchmaker it will turn into a oldie. There only 2 oldies, and it is by gender. The boy oldie is Ojitchi. The girl oldie is Otokitchi. They will come around age 16.
A oldie can not mate with Adults. They can only mate with a oldie. They will make a regular baby. BUT after the baby transfer it will turn into a Oyajitchi. He/she will skip the child and teen stage!
