An former colleague from my days at CBS sent this my way: a brief video he produced about a Palm Sunday Mass for children with special needs in New York City. As the website notes:
On Palm Sunday The Church of the Blessed Sacrament in New York City held a special needs mass for families. The church holds a special needs mass every third Sunday. Families are allowed to make noise and walk around during the service without feeling ostracized. In the video…one mother expressed the need for more services like this for church-going families around the country.
The website, Autism Speaks, has more, including links to resources that can be helpful. Check it out.
