This afternoon I was at a gymnastics with my daughters. I was sitting in the changing rooms as DD1 (7yo) was getting changed, whilst DD2 (4yo) was in her gymnastics class. 4 girls in that class including DD came in to use the toilets (without a teacher). Soon 2 of the girls started looking under the stalls, even crawling underneath the cubicle DD was using and saying things along the lines of “I can see her bum, eww you’re wiping your bum”, etc. Nothing you wouldn’t expect from 4-5 year olds but surely not acceptable behaviour regardless of the age of the child. I got up and said in a firm (not shouting) voice “We do not look under the toilets, that is not acceptable, please get up of the floor”. The children didn’t respond at all to what I said. There was another mother in the room who was on her phone and didn’t seem to notice/mind what was going on. At least not until I spoke up, she then came over and ignored me completely, she just said to her daughter “Don’t worry about it you’re fine let’s go back to class!”. AIBU in speaking to the child rather than finding a teacher/parent? In the moment I just wanted to stand up for my daughter, we’re trying to teach her about body autonomy and privacy and I felt really uncomfortable with this situation. AIBU to expect a bit more supervision from the teachers at this age?
