Aside from the obvious — one's in the studio and one's in your home — the main difference between these two types of newborn sessions really comes down to style. In-home sessions aren't really posed (think PROMPTS rather than POSES), while in-studio sessions are posed. Think of an in-home session as a laid-back "day in the life" with your new baby; think of studio sessions as the way we get those sweet, sleepy, squishy poses we all love.
Of course there's also the convenience of an in-home session, as opposed to an in-studio session. But if the thought of hosting a session in your home gives you anxiety, or if you're just not sure your home is the right space, studio is always an option. There's also, of course, the option to do BOTH types of sessions... and don't get me started on Fresh 48 newborn sessions!
To help you decide, here are a few of my favorite shots from an in-home sessions, and a few from an in-studio session.
