Just had to chime in and say, if you have an opportunity to go to a retreat this summer in the US, DO IT! We have been to several (three here, and one in France at Plum Village) and it was so worth the time, effort and expense. He is almost 80 years old, and won't be with us in body forever. There are children's programs for ages 6-12 and also programs for teens. If your child is under 6, they are welcome, but you will probably want to have two adults and take turns going to the talks. They can still participate in some of the activities. Thay is very interested in children and gives lovely children's talks at the retreats. He always does walking meditation holding hands with the children.
