Both kids photos

I find it is difficult to take both of my kids photo. I can't just ask them to sit quietly and give me a big smile. That is the most tough part every time I wanted to take their photos. This time I decided to give both of them potato chips. So at least they can really listen to me and I can take a good snap on both of them. I decided to ask Rachel to put her arm on Wilson's shoulder. This was what my parents did last time. Also remind me that, I always put my hand on my brother shoulder whenever we are told to take photos in two. Both my kids are busy eating potato chips and I have to take their photos fast if not they are asking me for another piece. Actually they eat faster than me!
