I love kids, I do. Kids are all so hilarious, and I have the energy to keep up with them. I prefer to allow kids to really be themselves, and run around with all that amazing energy they have. Unless they are newborns, then I just let them lay there and smile and stare at me and my camera as they try to figure out what is going on.
Capturing a kid having fun is the best memory for any parent to look back on, and for the kids to look back in the future when they're all grown up.
My favorite thing to think about is a son or daughter coming home for a visit when they are 25 or so, and being able to see that old photo I took somewhere in the house and them smiling as they remember what is like to be a child...
