Summer Care

I'm looking for summer care for my 3 children ages 7, 10 and 12. One of my children has mild special needs. Someone with experience with children with special needs would be ideal. They enjoy going to the park, swimming , museums, and crafts. Must have your own car and a good driving record so you can get the kids out and about. We do have an older medium sized dog. He's a sweet boy but a tad barky so must be ok with him. No cooking or cleaning expected other than preparing lunch.
