...not to change my facebook profile picture to a picture of my baby or my ultrasound. My profile picture is supposed to be a picture of me.
However, pictures of me and my baby or me and my ultrasound picture are not off limits. My timeline picture may be changed to a picture like that though :)
My profile picture will only be changed to something like that if I'm announcing our pregnancy.
I will not lose my identity by having a child or becoming pregnant.
