Good job Mama! Being a special needs parent is HARD and after reading through all of this I can see that you 100% wanted to make the best educated decisions for your son and it seems like it worked out really well. I hope you were able to get in a little R&R too, because God knows, SN Mamas need it the most and you do it solo so my hat is off to you.
I think that, unfortunately, the biggest threat/hazard in the kids clubs are not the special needs kids but the little punk kids who are entitled brats running around out of control, pushing, purposely breaking the rules, showing a lack of respect to the CMs, not sharing or not including the other children and speaking with harsh words without any excuse other than a lack of parenting/positive roll models in their lives. Those are the ones that concern me when I leave my daughter.
I am sorry there were so many people that took what you had to say and ran with fear instead of a lack of understanding and trust that you would never purposely leave your child in a situation where he would harm another child.
