How to know when the shoot's over when photographing young children:

Photographing children can sometimes be quite challenging. In the beginning, they can be so cooperative...sometimes...

and you might catch a cute shot of them in play...

or a sweet smile in an all-too-brief moment at rest...

but, then, they can quickly become distant...

or cold...

and the smile is gone...

and is replaced by grumbles...

and grimaces...and before you know it...

it's all over!
