I'm getting remarried and while my fiancé doesn't have kids, he is close to his sisters kids, more her sons than the girl because he always thought the girl was a little bratty. The girl is 10 and my daughter is 9. We thought it would be perfect as they were so close in age. Turns out the girl is very mean to my daughter and excludes her all the time. I've told my daughter just to ignore her and do her own thing.
But at my shower the other day, the girl was SOO mean to my DD. I just found out last night from a teenager that overheard some things and told her mom. Apparently the girl told my DD numerous times to go away at the activities that were set up for the kids. And then she told her that my FHs parents weren't her grandparents. His parents have always told my kids that they are their grandparents and want them to call them grandma and grandpa.
I feel terrible for my daughter. Obviously the girl is very jealous and she's lashing out. How do I handle this? Should I talk to the girls mom? Should I just try to help my DD learn techniques for dealing with this?
Our wedding is in a few weeks and I want this to be very special and fun for my kids. I would be devastated if this repeated itself on that day.
