The best thing that you can do to help with the success of your family photo shoot is to relax. I know it sounds so simple and a little crazy, but if mama is calm and carefree, it helps with the whole mood of the shoot and the kids will be calmer. Also, keep in mind that family photo shoots are meant to show the interactions that you guys have as a family so we actually want action shots of everyone connecting. If worse comes to worse, I can always use the magic of photoshop to switch heads and make for a great picture with everyone looking haha I have never had to reschedule a family photo shoot due to unruly children, so have some confidence that we will get a great shot.
