How do I photograph my kids?  Usually I chase them around with my cell phone and try to get candid photos.  If I actually break out the "real" camera, it's usually met with "Mooooooom!" and an annoyed look.  I usually resort to some sort of begging like, "Awww, come on, I'd love to have a pic of you on vacation!" and "Just one more, I promise!" which is why I'll be hiring a professional photographer to do our next family shoot, as should you!  ;)  Until I do, I'll continue with the methods below:

"Ok now jump in the air!  Get funky!"

"Squish together you guys!"

"Squuuuuuush!"

"Whatchu doin, mister!"

(expert stalking)

(more stalking)

"Oh my God, it would be so cool if you guys would lay down on the dock so I can test my settings before my client comes!"

"Do your 'Cool Guy' stance, yeah!"

Tickling!

Some methods that didn't work so well:

"Pleeeeeeeeeeeease look at me?"

"Are you guys laughing at me?"

"Welp, I guess that's the one that's going to ESPN..."
