Help! Birthday party

Hi friends, My wife and I just divorced and we are planning separate birthday parties for my son. This is so unexpected and I want him to have a fun day with kids his own age. I just moved to st Pete and I only know a couple families. I’d love some community support to give him a special day but I have so few kids to invite I’d love to meet new friends and just have a fun day where he can play and enjoy. As a single mom for the first time, I’m wondering if anyone has ideas or would like to bring their kiddo to a party when I plan it. Thank you!
