Here is something that will help you. (from binary)
After your V5 characters have been adults for 48 hours (2 days) (unpaused) you can use the Dating Show or marry by connecting to another V5.
Dating Show: activate the Dating Show in the TV icon. Select which adult you want to get married. The matchmaker will show a prospective mate. Agree or cancel the marriage. If you select cancel, you can check back for a different potential mate. You can check the Dating Show three times each day (at any time.) If you select to mate, your V5 adult says good bye to her/his siblings and they leave. Then she/he says goodbye to her/his parents (if you're on second generation or higher) then they leave. Then your V5 adult and the mate from the Dating Show get married, transform into parent characters, and have randomly one, two, or three eggs.
Mating by connection: activate the Connect icon. Select V5. Select Marry. Now, you game either Give or Accept a mate. If you have more than 1 adult character on your V5, you can give one of your adults to be a mate on a friend's V5. If you're going to be getting a mate from your friend's V5, select Accept. Note: the two families must be at the highest level of friendship in order for this to work. The V5 giving the mate will see that adult leave their screen. The V5 accepting the mate will see the mate arrive on their screen. Then the adult accepting the mate says goodbye to her/his siblings and they leave. Then she/he says goodbye to her/his parents (if you're on second generation or higher) then they leave. Then your V5 adult and the accepted mate get married, transform into parent characters, and have randomly one, two, or three eggs.
After they mate, you won't see the parents often. They'll show up when you give the children medicine, feed the children, and during some certain time-of-day animations.
