Wow, people are ridiculous these days. I think you handled it well. Let her look them up. My dc parents love that I take the kids outside. We live in Canada, does she want them to hibernate all winter. I had a parent not choose me once because the grandmother saw me walking with the kids to school everyday and didn't want her grandson (3 yrs old) to be out in the cold.( Bubblewrap generation). I have a covered wagon, blankets etc. I'm glad I didn't have to deal with them.
