Kitt has got stubborn a lot

Kittu has got very stubborn. She does not listen to me. She is getting older day by day. After three days is her birthday. She is not aware of this. How can she know this as she is a little kid only. I will distribute chocolates in her school day. She is a lovely sweet angel. She has got many friends in her school like Prtham, Utkarsh, Joe, Anshika, Garima etc. She often tells me about them. I sometimes think that when she will grow up and start going to school then will get occupied with her friends and life then what will happen of mine!!! as at present I am her guide and decision maker. Sometimes I tell her that I won't let her to marry otherwise I will get alone.
