Good question. We mostly communicated with close family in the early days who spread out the news, but we have a big family. then I found something called https://www.caringbridge.org/ to update a large group and include pictures. I found it helpful too almost like a diary for me. Maybe look into it. Good luck ❤️
"So Zack and I have some news, our baby girl is here. She is currently in the NICU in rough condition she is a little fighter and we are so in love with her already." I posted that the day our daughter was born after I was able to see her. I personally didnt give alot of updates, I would tell my sister updates only and she would spread out the information so i could focus on healing and being there for my daughter. I was very picky with what information I even told her, and it was like once a week I gave anything new but we wanted to keep everything to ourselves until we knew she was going to be okay.
