I have found when taking a family's portrait that involve small children, like Avery who is 10 months, that you pretty much have to let them run the session! If the they get too tired, too hungry, told to sit still too many times, don't have enough interaction then in seconds your family session can take a nose dive. I even downloaded an app that made farm noises just to help the session when it hit a small lull, but all it took was playing with a few leaves.
