I've put this here rather than on any of the main boards as I don't want an onslaught of people saying I'm horrible or that I'm implying he has nefarious intentions. I'm really not so I hope it doesn't come across that way. It isn't an attack on him, just me looking out for my DD (and maybe some unintentional projection on my part as a CSA survivor) again, I'm not saying he's planning to do anything.
I have a 3 year old DD who isn't yet toilet trained. I have noticed that DSS who is about to start secondary school always makes a point of coming over and looking when I'm changing her. He isn't discrete about it so I don't think he's trying to hide the fact.
I've raised it with dad before who thinks it's innocent childhood curiosity which is normal among siblings, and it may well be, but it makes me uncomfortable.
The bathroom is too small and awkward to change her in so It's always the living room (when the older kids aren't in there - but they happen to come in to) or the bedroom, again which they come in to. Dad seems to forget I've raised these things and will happily change her in the same room that they are already in. He'll just walk right up and stand over her.
Would I be unreasonable to have a talk with him myself and ask that he respects DD's privacy when she needs to be changed?
