Many of us don't know what to do with our hands during a photoshoot. The only thing not to do here is to put it by the side of your body.
Try these simple poses, hold your spouses hand, place it around his/her waist, hug your kids, place them on their shoulder, place them in your pocket, put them around your waist, etc... anything but by your sides.
With these tips, you will do great with the family shoot. Do not forget to print these amazing photos into canvas or/and acrylics. They will be a great family heirloom and a constant reminder of your family love.
