I have a toddler myself, and I know that children often have a mind of their own and won't do what you want no matter how much begging!
So I, as a mom (and teaching helped too!), have developed a different kind of super power: PATIENCE! I sit and stalk my child, camera in hand, while she is playing like a tiger stalks its prey.
I take shot after unsuccessful shot;
some where she is turning her head away,
and some shots don't even have her in them as she falls at the last second!

I may not be able to get the perfect posed shot very time, but when I pull out my camera to capture my toddler, I know I will always get the real her. And that, after all, is what I am after!
