First you need a baby girl. Then when it evolves into a child try taking good care of her to try get into the UraMeme family. When your Tama evolves into a teen, you need a UraYoungMemetchi or a UraYoungVioletchi to be in with a good chance of getting her.
Now just raise her Funny skill points so they are higher than all the rest.
Hope i helped, and have a great tama-talking day!!!
