Pregnancy Announcement Advice (trigger warning infant loss & stillbirth)

I’m looking for some advice around a particularly sensitive topic and I’m sorry if this brings anything up for anyone in reading this.

About a year ago a close friend of mine lost a baby late term. She has had a hard time coming to terms with her loss, which is completely understandable, and she is very much still grieving. I have been checking in with her, dropping meals over, and trying to be as supportive as possible without prying when she doesn’t want to talk about it.

I have another friend who lost a baby as a newborn.

I have recently found out that myself and another friend are both pregnant and have due dates about 3 weeks apart. We have to break this news to our grieving friends and I would like to do it in the gentlest way possible. I am incredibly happy but I am feeling horribly guilty at the same time. What is the best way to handle this? I’m not sure if we should tell them together in person, or if sending a joint message would be better so they have time to process it privately? I would appreciate any advice or insight on the situation that anyone can offer.

Thank you so much
