I came across a very helpful article for family photo shoots. My favorite tip from the blog post:
6. Have fun with your family.
Advice for your clients:
Don’t be afraid to pick up your children and toss them in the air. Give your wife a sweet kiss on the check. Tell your husband how much you love him and appreciate him for being there for your family. Have fun. Laugh. Giggle. Joke. Embrace. Kiss. Snuggle. Play. Doing these things will allow the photographer to capture the emotion and true beauty of your family. Leave the stiff “cheese” faces for Aunt Marge at the next family reunion. Show your photographer who you really are, so that she has the opportunity to capture your love through her lens.
