Quite honestly, the conversation did not lead very far. Actually, she pretty much ended it when she picked up dcg and she hit mom in the mouth and then went "awwww" and gave mommy hugs.
I used that exact moment as an example to point out my concern. She is doing something bad, to then do something good. (taking the paci to make baby cry and then give it back)
I talked to her again this morning quickly at drop off and she runs in and pats everyone on the head. I told her that I think that I am going to have to stop any form of contact between her and the other children, because at this point, she is not able to decipher what is gentle/good and what is not.
The mom just says that she is a gentle giant and then had to rush off to work.
