Name changed as don't want to be too outing.
I know I'm probably going to be flamed for this but I have a 7, almost 8yo who thinks someone else is her dad. And her elder sister also thinks said person is their sisters dad.
To put into context, eldest knows who her dad is (ex husband). She saw him until she was around 3 and then it dropped off until nothing. She remembers us living alone. During this time I (stupidly) had a one night stand which resulted in her little sister. Very early on, little sisters dad said he wanted no involvement so I went it alone. That's how it stayed until youngest was 14 months, oldest just under 4 when I met my partner.
Both girls call my partner by his name (been together 6 ish years), never dad. But recently my eldest commented that little sister has the same eye colour as her dad. Wrongly, I had presumed that eldest would remember our alone time and therefore wouldn't presume partner was sisters dad.
I'm from a family with skeletons in closets.
Both grandparents grew up thinking their dads were biologically theirs only to find out later they wasn't so ive said right from the beginning that the girls need to know the truth. But...when's the right time? I've never needed to correct my eldest as she's not raised it, but I can't mislead her. But if I tell her, she will tell her sister who is very young minded for her age. There's no doubting I will tell them, because I will...but how and when? Has anyone else been in this situation? Be kind please.
