My 6 year old says it's unfair that one classmate gets to leave the room for breaks
There is a boy in my son's class who goes out with an assistant for short breaks during the day. I know nothing about him beyond that, and I don't need to. My son, however, has decided this is unfair, because he would also like breaks. I want to give him an answer that is true and kind, and that doesn't involve me guessing at another child's needs. So far I have said 'different children need different things', which he finds unconvincing. How have you explained this kind of thing at this age?
