I love the tween set

So here's my question, when do kids become tweens? I swear if I could photograph them all day I would. The Wintons are the most fantastic family. Their kids are so beautiful, fun and totally uninhibited. I felt like all four kids really let me in. The best part about this shoot was the fact that Patricia and Nick just left me alone with the kids so they could just be themselves. I think the images clearly show that. I love when kids smile but it needs to be natural and not coached. As you can see many of these image don't show smiles of any kind and they are much more dramatic than with a force grin. Their children rage from ages 15 to 6 and I swear they are all so amazing. I'm attached to them for sure.
