I need advise PLEASE?

Ok I work for a school as a Para educator. I have worked with the same boy since he was 4 and now he is soon going to be eleven. He is autistic. I ride with a woman who is much older than me because it saves gas and all that but that is not what it is about. She always has comments about how my cl works with our kids. Like one of our kids has a terrible home life and he comes in very sleepy and we allow him to sleep because he literally falls asleep sitting up. (we have brought this up to SRS ) But she is like I don;t know why they let him sleep, and today she brought up that sometimes our kids do not go to recess ( i use this time to gather materials and I am one on one) he gets inside recess in the cl while I do that where I can watch him etc. I am a one on one para the para's in our cl di not get breaks we are with the students all day. To make a long story Straight we have always had people that do not understand the way we work with our kids they think that we just let them play all day and that is not true. We have to work with them in different ways. Now I really want to tell her to stick it up her but I do not want to cause waves. So how can I deal with it in a dignified way? I really hate when people criticize when they do not work in our cl and really do not see what it takes to get children with learning disabilities autism and behavioral problems to get things accomplished. This lady works in a regular ED cl with a blind girl that is super smart but just cannot see. The kids we work with are more of a challenge because of their many challenges.
