I’m confused about something my mom says.

I don’t wanna get falsely banned again so I’m not sharing anything personal. But for some reason, my mom thinks I’m “too small” and apparently that’s the reason why inserting 2 fingers burns?? I don’t think so…plus she says the same when it comes to toys, she thinks my body is too small and I’ll get hurt so I’m not allowed to get any. Which really sucks because I don’t think that’s the case AT ALL and I’ve used my fingers for too long and want to explore. Why is she saying this?? 😑
