If the girls are excluding your daughter and whispering and not doing anything else, I'd say that they're just not be nice right now. That might change in a few days or a few weeks if your daughter maintains her cool. Little children are often unkind due to their immaturity. They are fickle too. If your daughter enters a victim mentality, however, these kids and others will continue to pick on her. Right now, you can advise your daughter to look for other girls to play with. She should hold her head up high and ignore the whispers of this little group. She should continue to be her happy, busy self even if that means looking very busy at recess with a great book. Let your daughter know that this is probably a phase the girls are going through and she can just wait for them to move through it. She shouldn't look for their attention right now. In summary, I would not call this "bullying." I would call it "not nice." Your daughter can survive it on her own.   Sarah Chana
