Play groups. Go to the park with your daughter and encourage her to be friendly with the kids who are there. You can be friendly with the other moms who are there. Say hi, make small talk.

I met so many moms through having kids. I put my kids in preschool when they were 2 or 3, and I joined play groups with those moms outside of the preschool.

We'd go to places on vacation and I'd encourage my kids to make friends with other kids in the pool or in the playground, and I'd talk to the parents.

Just mingle, and teach your daughter to mingle.
