Photoshoot query

Hi, I’m thinking of getting a family photoshoot but I don’t fancy the idea of the photos being shared on Facebook. It seems to be done by all photographers, is it compulsory?

Also- would you recommend having a family photoshoot as soon as the baby is born or waiting a few months? I have a 2 year old and I want sibling photos and family photos rather than newborn ones. Thank you!
