Our church, Epworth United Methodist Church in Huntsville Alabama, totally embraced my child and a few others into their program. They also accepted our full-time aide (which we paid for) and allowed us to train the teachers to give our kids the best possible early intervention in a fully inclusive program.
We loved it. Our kids thrived there.
The key is teacher support and support of the director. The trained aide was the element that made our child so successful.
Good luck.
