First and foremost, I would say not to stress too much over it. We are taking photos of you, not taking real estate photos to sell your house! This means if there are areas in your house that you don't want pictures of, we simply won't capture it. My suggestions usually include removing items that you do not want to be seen such a clutter, the kids' toys, and anything else that may be lying around. The space will look much bigger once you do and the photos will have fewer distractions. If there are pets in the house, running a Swiffer sweeper right before the session will remove their hair from the floor and keep it handy for the photoshoot as well. I use it while taking the photos to do a quick sweep instead of using Photoshop to eliminate it post-production. It is also a good idea to keep screens turned off during your sessions. However, music is always welcomed and when combined with a nice relaxing scent, it's always a great atmosphere to keep everyone relaxed and enjoying the moments. while not necessary, it is also nice to have a full set of clothes for changing into in a separate room. This helps to eliminate any stress and prepares you for the unexpected. Other than that, you can pour a cup of coffee and tea and let the fun begin!
