Two my childrens house mothers are not getting along?

They have been house mothers together for over two years. They each have had one child and I treat them the same. As part of our family, I have read them pages from The Golden Light teaching them how to ascend to righteousness. Anyway, now they are always fighting about time with me even though they both have their own living quarters. They talk about going outside or calling outsiders alot. Any ideas?
