Ok..so not to drip feed I will put as much down as I can..
I have 4 dc, eldest isn't dh but treats them all equally. Eldest dc has regular contact with his ddad and dsm.
Dh has 2 dbro..one of which has a child that also isn't his but 2 are his own. Me and dh treat them all As nieces and nephews regardless of biology.
For the second year running now, this dbro and his oh have only put auntie and uncle On cards and gift tags to their biological nieces and nephews (mine and dh children together). And my eldest, just signed them with first names.
Now..I'm not sure if I should be rattled by this but it really bothers me. We aren't stupid and we know my eldest didn't dh but to refer to him as being different to my other children really bothers me.
For context, my eldest is really close to said dbil, more so than my other children, so I just can't get my head around why they would refer to themselves differently than to my other children.
Fwiw, I ended up taking the gift tags off all my dc presents to save eldests feelings.
Dh says he will speak to his brother if i want him to, but also says we should just let it go and be the bigger person..but surely this isn't always the case when you can potentially hurt a child's feelings.
I only have dh to speak to about this so would like impartial views.
For the record, his other sibling all put the same on gift tags and cards regardless of biology.
