Chase Doesn't Like to Lose

We've discovered that Chase doesn't like to lose (who does)?  Last week Chase and I were swimming at the club and we were racing from one side to the other.  I let him win a couple of times and then I won.  He didn't like that at all.  He said "no mama, you're not supposed to win.  I'm supposed to win."  

A few days later he wanted to race down the stairs.  He was on Greg's shoulders as we raced down.  I was the first one down so I said "I beat you" to which he replied, "you beat daddy mama, not me."
