Saved the Best for Last

So why is it that when you plan and prepare to take pictures they don't turn out as good as when you do impromptu pictures?!?!? These were not planned, but they turned out the best! So, next time I go have pictures taken, I am taking my nephew Christian with me to get him to have her laugh like this again. I don't know what he was doing behind me....I just told him to keep doing it! Every time I look at them I can't help but SMILE!
