I was dropping my daughter off at her daycare this morning and we were walking around the playground. There were 3, 4 and young 5 year old's on the playground at the time. It was pajama day and I had noticed 3 or 4 of the older girls had on long Princess nightgowns. We walked past a group of the 5 year old's and I heard one say to another, "Aren't you sad you didn't wear your nightgown today?" The girl was wearing pj's - they were just shorts and a tee shirt. She responded by saying, "This is my nightgown, I like it." And sounded sad. I noticed her later standing off to the side with her arms folded and a sad look on her face.

UGH. Five year old's. Already being mean girls. I hate it!!

How early have you seen this?
