I’m worried my 4 year old is being too mean too often to her friends.

I have a 4 year old daughter that I’m noticing is being excessively mean.I understand that toddlers, and children in general can sometimes be needlessly mean to each other. I feel that I’m just seeing it too often lately.When I witness these things happen I take my daughter to the side and explain, in simple terms, how she is making her friend feel when she mistreats them. I’ve reminded her of times when she was sad after others had treated her poorly. I tell her about when I have been treated poorly by my friends, and how that made me feel. When she does do nice things, and plays well, we give positive reinforcement as best as we can. We have even intentionally limited interactions with 2 children on our street that we have noticed don’t commonly treat people well.Her preschool teacher has recently mentioned that she has had to take my daughter to the side for some “talking to’s” about how we should be treating our friends.I’m feeling pretty powerless about all this. Just looking for some outside info. Book reference. YouTube video lectures. Personal stories...whatever...just needing a little help.-j via /r/Parenting http://ift.tt/2iD7PuM
