Seriously, Ive heard this sooooo many times that newborn shoots are only done when the baby is maximum under 15-20 days old. I personally have photographed so many babies who are even upto 2 to 3 months old and been able to manage several newborn poses with them. You need to be calm around the baby. Understand their needs. Have the room very warm and cosy so the baby feels sleepy and everything will go well.
Little Emma was 1.5 months old when her mummy called me to Long Island, New York to do her photoshoot and as you can see here, we did very well with getting lots of newborn set ups and poses through.
It was so wonderful photographing them in the comfort of their home as well. Feel free to contact me if you wish to book a newborn or family photoshoot with me. You can also click on this link to book a slot.
