Sitter sessions are for babies who can confidently sit up unsupported typically around 6 to 8 months. These sessions will take place in my home with a outfit provided if you wish. What makes this session so nice is that babies around this stage are becoming very smiley, playful and curious. The best time to do these sessions is when baby can sit up unassisted but before they are crawling. This is a great time to come in since this marks the halfway point to their first birthday.
