Name-changed for this because if someone knows me IRL, it's probably going to be obvious! Going to be a bit long because I don't want to drip feed.
Background - DD (8) has never known her biological father, no contact attempts from him ever, he's just not interested. DH has been around since DD was a few months old, he's always been Dad to her. DH adopted her officially (with biological fathers consent), and that was completed last month. DD changed schools a couple of months ago, so we informed them about the adoption process because we thought it was best they knew. She will have the same class teacher next year because it's a small village school and each class is two years, if that makes sense.
However, the new teacher is insisting on referring to him as "your step-dad". I did initially presume she was doing it to avoid causing offence, so I approached her and explained the situation, but nothing has changed. DD says Teacher has even corrected her when she's said something like "My Dad supports Newcastle".
So I genuinely don't know. Am I being a bit precious about this? It was never a problem at her previous school despite the adoption not having happened at that point. If it wasn't upsetting DD we'd let it go, but it is really bothering her, she came home in tears from making Fathers day cards the other week.
AIBU to expect them to respect that he's her Dad? And if I'm not, has anyone got any suggestions for what I should do? Approach class teacher again, write a letter to her or speak to the head?
