Playdates

I loved our old neighborhood.  It was nice there were lots of little kids, always playing outside, it was easy for the kids to make friends with the neighbors. Of course we had outside playdates our weekly one with Kyah and the random ones here and there with other friends.
I have had a hard time with playdates since moving especially now since the kids started school. I fee like thats the only way our kids play with the neighborhood and church friends.  Everyday Kira wants a playdate, she talks to kids in school but I don't know there moms or where they live. Or the girls on our street will have playdates with other school friends and so Kira is left home sad.
I don't know what to do. This is not what I did growing up. I don't want Kira feeling like she doesn't have friends because she doesn't play with a friend every day after school.  I want her to always feel happy about who she is.  Don't get me wrong Kira is a very confident girl, she has friends I just hate when she feels sad for having no playdates.
