My mom (a SAHM) has this mentality that daycare kids are mean. She said she could always tell the kids that were in daycare because they just had that fend for themselves mentality. She said even though they obviously were around other kids, they were very rough and harsh.

I am starting to see signs of this in my 18 month old. She attends a larger center, so I don't know how much direct teacher attention/activity they get.
