How to create profile for second baby?

Hi, I am trying to use Nanit camera for my second baby but want to retain all of the data that I have collected of my first child. I have an active subscription for my first child.

How do I create a second profile for my newborn to use with my existing nanit? How do I also ensure I don’t loose any data (growth and milestone videos, morning pick-ups etc) for my first child who has been using the camera since birth until now?
