Also look at the make up of the group now - age, sex, personality. Often it is the oldest or youngest in care that is the primary issue or often the one that is sort of left out once you factor in age, sex, interests. While in theory there might only be 6-12 months between kids in age it is a lifetime in developmental stage and some don't mix as well as others.

But for sure once we gain back all of the minutes we spent dealing with that one child and the other children don't have to suffer through us dealing with each other that everyone breathes a sign of relief.
