Using Nanit for second baby without losing data of the first born

Hi, I am trying to use Nanit camera for my second baby who is due in February 2023 but retain all of the data that I have collected of my first child who was born in March 2021.

How do I create a second account for my new born and use my existing nanit and ensure I don’t loose data (growth and milestone videos, morning pick-ups etc) of my first child who has been using data since birth (March 2021) to date?
