What's the thing that makes you so happy about your child?

Hi, It is the fact that she is the one person in the world for whom I am the most important person. I know this is a selfish one but this is it. Apart from this, I must say, there cannot be just a thing that makes me happy about her. I feel happy seeing her doing each and every thing. Be it her tantrum, talking sweetly, screaming, eating, sleeping, dancing, not dancing, sulking.....everything makes me happy unlimited. :)
