Thanks everyone. I just want to be clear, I don't interview based on sex either. I am looking for an older child for Sept but if a boy came and was a fit I think this would be better for my daycare and the group makeup (offer more balance as there is currently 5 girls and 1 boy).

So I emailed the parents (they don't communicate directly as they are recently divorced) and just gave an update as to how his week has gone so far after being off on vac. I was very factual e.g. "dcb starting saying today he wants boys to play with which came as a surprise to me as he has always preferred dd even when there have been other boys in the program. I reminded him about our park/library outings and all the other boys we see out in the community etc." The mom actually said that she doesn't think the boy thing is his issue, he just overheard us (meaning her) talking about his being the only boy...so that is good news. I got the answer I needed, found out her stance on it and she now knows not to mention it again as it causes problems for him...problem solved.
