My biggest advice to parents when it comes to photographing their children is to keep it short, make it fun and know how to roll with the punches. Inevitably, there might be tantrums, uncooperative moods, soiled clothing or things just not turning out how you envisioned. What I can promise is if you are fast, patient, persistent and playful you can capture your children in all their many moods. Which in my opinion is much more satisfying than smiles all the time anyways. (These are not my children, but pretty adorable ones nonetheless.)
