@Fairy - speaking as a step mum myself, don't let some of these comments get to you, its really not worth it. Regardless of the "name" put on your family, no one here knows your family dynamics but you and your family and they are the ones who matter, not us.
I did post earlier - my advice was put the picture up, its not hurting anyone I have 2 DSC, i have pictures of me, OH (DSC's father) and our child up on the wall, i also have pictures of OH with bio child, oh with DSC, all manner of differences going on our wall....do any of us care, no.
We all know our place in the family home and we are more than comfortable with it. We know we are loved and that's what matters to us.
Put your picture up and enjoy the hell out of it.
on MN no SM will ever be in the right, no matter what they do, so please do not let the haters get to you x
