I am just wondering what you all do with this aspect of two year old behavior, if all two year olds behave like this, and your thoughts about teaching children to share.
My daughter is about a month over 2 years old and is a pretty easy going, friendly child, doesn't have tantrums or anything but occasionally getting mad which she generally gets over quickly. She is an only child and stays at home with her dad, so doesn't get that much interaction with other children.
I'm not worried that something is particularly wrong with her behavior, it seems like all children her age I have met have this possessive thing going on, "that's mine" and grabbing things from others. I have not spent a lot of time around children before having one, so I'm interested in ways people deal with this. It is especially of concern to me when she is with a baby or smaller child and she could hurt the child- I feel I need to intervene. But also, I wonder why they go through this (I'm assuming- hoping!- it's part of development), and what way to react to it, and what my child might learn from my reaction.
