Depending on where you are going to live here in Ft Myers, there are 4 chapters of MOMS Clubs here and 3 in Cape coral, 1 in Bonita, and Naples too. It is a non-profit support club for moms. They have events mostly during the day fo the kids, playgroups, field trips, Moms night out once a month, seasonal parties too. The Intl web site has more info, but not all chapters are listed on the site, so just send them your info on your address when you get it and they will give you the contact info for that area. www.momsclub.org
There is a Gymboree here also and a couple of open gym places too for kids....
Good luck!
