My DD has a good neighborhood friend she loves to play with. Recently, when my DD has tried to arrange playtime with friend, mother has said the girls could only play if my son also played with her son, because the boy is jealous of the girl's time together. Problem is, my son is 12 and her's is 7, so they are not a particularly good pair. While my son is patient and kind when the other boy is visiting, he wouldn't normally choose to play with the younger child. So DD can't have a playdate without her brother sacrificing his afternoon as well. Not to mention my having to supervise another child who is, um, more difficult than I am used to. How the heck do I deal with this? Either way it plays out it seems unfair to one of my children.
