Why are kids so selfish?

I am taking my daughter shopping in a few days. I told her I will be buying her some clothes from sears and hollister. Then I tell her I will be buying her god sister clothes as well.. She gets so mad and was like no that is not fair she can get cheap clothes you can afford to buy me clothes now. So I had to remind her that her father is always giving us money. It would not be right of me not to pick his daughter up something when I take my daughter. She needs to stop it with this selfishness or I will stop him from giving her money. He gave me his last money yesterday to put towards my back rent. Plus today he is working on giving me the rest. I would not feel right knowing he can't get his daughter nothing new and I could. I don't do stuff like that. I am a giver in life and she knows this.
