OPINIONS!!!

Okay so I need some opinions on posting your babies pictures on social media once they are born, some people post them right up there for everyone to see and some don't and at first I was all for pictures being posted as soon as they were born with the weight length ect. But now I'm starting to change my mind I'm starting to feel like it should be a very private thing that is only shared with family and close friends after all if your important enough you will come to see the baby at the hospital or the first few days he or she is born and if not well then you must not be very involved and you don't need to see he or she anyway! And it kinda freaks me out to think that you never know who is seeing that picture of your newborn so what's everyone else opinion is it okay and the norm to post their pictures all over social media or should it be kept private??
