Honey, two year olds just like their Mommas. That is life. Just you wait though. It doesn't last forever. That little boy will dump you like a hot potato for his Dad when he gets older. It is nothing to get upset about, it is just life. If you want him to go running for his Dad even quicker, have another child. That will do it quick!
Enjoy this time that he prefers you. It won't last forever. One day he will be off and going and you will miss him needing you so much.
