Sitter or six month session whatever you wanna call it basically the same thing... I absolute love watching all of these sweet babies grow. I always request that the baby isn't wobbly. Some are sitting up very well at six months and some need just a little more time so we wait until they are seven months, I care more about their safety. There are several different poses but mostly on their back, tummy time and sitting up either with assistance of a bowl, box, or bed. Typically each session doesn't last longer than an hour with two to three outfit changes. I ask for you to schedule them at their happiest time: either first thing in the morning or right after their nap with a full tummy!
