My boyfriend and I have 3 daughters (2 his and one mine, ages 14, 13, and 11) from previous relationships. They all live with us. My daughter's dad is stable and well-off financially, and involved in her life. My boyfriend's girl's mother is not; she was recently homeless, and her involvement with her girls is sporadic.
My daughter recently came home from her dad's for Thanksgiving, loaded down with new clothes. This has (understandably) caused resentment from his kids.
Christmas is coming. My daughter will be getting packages in the mail of gifts from her father and extended family. His daughters in all likelihood will not.
Any suggestions on how to diffuse the potential drama? I know other people must have done this before...This is our first Christmas together...Would like it to be happy!
