There is one problem in breeding: There are randomly moving NPCs off-screen. Technically you don't start on a differend PID frame but by the time you can control the menu they may have advanced the frame.
We think the Time Finder should be self-explanatory for you by now. Just don't forget to check International Parent in the case you have one.
In the main window, select the correct method, depending on a parent being international or not.
When you are in the game, enter the menu as fast as possible. Then you have to listen to the Chatter to determine on which frame you are. You most likely will not be at the starting frame because or the randomly moving NPCs. When you are on your desired frame, exit the menu and talk to the daycare man as fast as possible.
