Step dad bathing 8 year old DD

[Amiovereacting82]

I went out tonight to collect my older DD, before I left I told younger DD to relax with step-dad and I'll help her bath when I get home.
Got home, not very late, just after 6, and DH had already bathed her.
A couple of times recently I said I felt -as DD turned 8 a few months ago- it's less appropriate for him to be in he bathroom at bath time/ do bath time (admittedly DD doesn't need much help bathing now but likes me to be there).
I feel really really uncomfortable with this, like he has crossed a boundary that was really important and that I mentioned more than once.
He said DD asked him to, but he's the adult!

For context he has been in DDs life since she was 3 and is like a dad to her as her father sadly wasn't interested in being involved.

DD is a very young and vulnerable 8, nothing diagnosed but suspected ND.

I feel so uncomfortable with this - he knows I'm very very protective of both my DDs

Am I overreacting and being neurotic?

This made me cry. What happened with my foster parent who went on to, you know the rest

I can explain this but do have another think as to why.

We know that quite a large number of men are attracted to children. Some to girls, some to boys and some to both. Some to some ages, some to others. We know that some men are sexually attracted to girls at the specific stage of development that OP's DD is now at. Based on that knowledge, there must be a point for such a man, where he goes from looking at a little girl as a little girl, to seeing her as a sexual object. We know of fathers who start to abuse their daughters at a certain age. Before that, they may well have treated them in the way that men who are not paedophiles treat their daughters. See here:
"The Truth Project found that for 35% of participants, the abuse started when they were between four and seven years old. For another 32%, it was between the ages of eight and 11, meaning more than two-thirds of abuse started before adolescence.
Nearly half of all abuse happened within the family home (42%) perpetrated by a family member (47%). The next highest location was the child’s school (15%). Aside from family members, almost always the abuser is a person in a position of responsibility for the child"

Those statistics are very worrying turtle

I'm sorry to hear that thehills

But did you talk about privacy around her step Dad? If you had a general conversation about strangers it wont have clicked for her that it includs her step Dad.
