Hi,
I live in Salt Lake City and last year I joined the MOMS club of Salt Lake. I was able to join a playgroup with children the same approximate age. The Mom's trade off hosting the playgroups once weekly in our homes. In the warmer months we can decide to meet at a local park instead. They also offer feild trips, park play days, mom's night out activities, ect. My children are 6 mo and 22mo. The playgroups have been great this winter. Since you live in South Hollady, there is a Murray/Holladay chapter. Here is the website: http://murraymomsclub.50megs.com/
My older son used to love Gymboree Play
Center(Highland and 48th-ish South) It is alot of fun. They have a discount for siblings.
Have fun!
