Her biological dad, who left us when she was six months old, is in her life, marginally, but she considers stepdad her "real" dad. She is 35 with children of her own, also treated as "real" grandkids by my husband.
In this situation, it's reasonable to treat a stepchild like your own kid because the stepchild is young enough to bond with...it's in cases where the child in question is already in their teens and the new stepparent is being asked to pay their expenses which is not reasonable.
