Are your kids in sports?

I recently saw a comment under a video - the mom said she put her son in jiu-jitsu to be able to protect himself if needed. She said jiu-jitsu is really good for kids on the spectrum. She mentioned it builds self esteem and they learn how To defend themselves since unfortunately our kids can be a target for bullying. I'm really thinking of doing this. I don't want to teach him that violence is key but if a kid is trying to hurt him or put their hands on him - he will need to defend himself. She also said he had a lot of meltdowns in the beginning and would just watch but eventually he participated and now 7 years later he is a grey belt ! Any of your kids in sports?
