Vaughn - that first image is one of my favorite ever.
I enjoy images of childhood just about as much as anything else there is ... Kids are about as real a subject as you will ever shoot. Do what Suzanne and I do - just turn the camera to them and get some inspiration!
Mine are 4 and 11 and don't even pause when I pull the car over and exit saying "just one second - have to get a photograph of this"... my husband is even tolerating it now (it only took 15 years).
