My Grandson is 2y/o. In general it's a good idea to never photograph other children without parental consent. However at my Grandson's 2nd birthday I took quite a few photos of him and the other children playing with the new toys. I know everyone and their children that showed up. Afterwards I printed out photos and passed them around. Quite a bit afterwards as I shoot film so it takes time before I can develop and print out the pictures. My photography is similar to most family types. I take photos of my family, the things we do and the places we go. If we go hiking then I take pictures of the hike and a few pictures of us hiking or sitting on a rock etc. I will probably take a picture of the rock. I do not post family photos on the net but here is a typical photo that I would take while hiking which we do quite often. Pinnacles National Park which is just a short drive down the road. B/W film is my medium.
