i am a mom to a 4 year old. she needs someone to play with,but all the kids on our block are way older than her. i am trying to find a playgroup in western suffolk,but i am confused on where to look, what to pick, and what goes on at a playgroup get together. any tips, info or suggestions would be greatly appreciated! also, is there a difference between prek and play groups when it comes to a 4 year old???
