A full newborn session can last up to 2-3 hours. This accounts for feedings, diaper changes, and anything else that might pop up. My most common package is a in-home newborn session with clients usually spending anywhere from $350 – 2k+
I do offer a mini newborn session these generally lasts 30 minutes and we do as much as we can in the time allotted.
It all depends on the baby and what your goal images are. Some babies sleep the entire time and let me pose them while others are awake the whole time.
