Some babies sleep throughout a session, some sleep for a part of the session and some are fully awake. I It's much easier to shoot and handle sleeping babies, but I also love capturing awake babies too. Each bay seem to have these dark navy blue eyes that eventually change as they get older.
As a professional newborn photographer I go with the flow. I do consult with parents ahead of time about props and colors as well as my workflow. I also provide a detailed what to expect session guide. There are a few ways to get baby to sleep.
Shooting between 10 and 14 days old, keeping my studio very warm, using white noise, wrapping baby comfortably and a lot of shooshing and rocking.
