Identity

At what age do we know our identity? I remember years ago when my son sent me a video of my oldest granddaughter saying her full name. I still have that video. It was the cutest thing. Last night my other son sent me a video of my youngest granddaughter saying her full name. He asked her what her name was and she answered as clear as a bell. She knows who she is. She said the names of her brother and parents. She is learning the concept of identity. It is a sense of belonging. It was only a few words, but hearing those words made me see just how fast she is growing up.
