the best thing i have ever done was join the YMCA, they have SPARKS, which is 50 minutes of group activities such as kickball, volleyball. basketball, twice a week, also swim lessons, swim teams, soccer, baseball, volleyball. besides the YMCA my children are involved in tie kwon do, music lessons, church group activities, 4H which is sooo GREAT, dance, gymnastics, tap, the YMCA is so affordable and offers an unlimited amount of options, also they offered group sign language classes we took , a babysitting course for my older children, first aid, CPR, , 4H is great to get involved in, I am a home schooling mom, I also was worried about socialization, so i guess maybe we overdo it, but my kids love all there activities, also find other homeschooling parents in your area, they have meetings, support, and lots and lots of ideas, but definitely join the YMCA, good luck, you have made a great decision,
