I've been meaning to write about this subject for awhile now. Every time I thought about it, something happened, and it got put on the back burner. I'm glad you mentioned it.
Through lots of research, I was able to find only one not for profit summer camp that takes kids with all kinds of disabilities, including kids who are bipolar. We sent difficult child 1 there for three weeks last summer. He was very ANGRY that we were sending him to camp!!! Unbelievable - he actually had a great time!!!
Even though this camp is a not for profit camp, it is still really expensive - about $1000/week!!! However, it is still better than $3000/week!!! We couldn't afford to send difficult child 2 there. We sent him to a local YMCA day camp for the same weeks that difficult child 1 was at overnight camp.
For us, it was a way of preserving our sanity!!! It made more sense for us to send our difficult children to camp than to take a family vacation. While they were away, easy child and I spent lots of quality time together. husband had to work but, even so, with only difficult child 2 home in the evenings, life was so much easier!!!
I highly recommend this camp. The staff is well trained and great with the kids. Many of the kids are on medications. Medications are given out four times per day. You just have to make sure that your child's medication can be administered during the already scheduled times.
I know I can't give you the name of the camp here. It is located in New York. If you are interested in learning more about it, send me a private message. I'll give you the web site which has lots of info on it. WFEN
