You say I haven't ignored her loss people just deal with things differently I cried a lot when I found out just didn't know how to go about it.
In her eyes, though, you have ignored the death of her baby - you've not even said that you're sorry it happened. Not knowing what to say is not an excuse - just say you are sorry, or that you are thinking of her. Or Google any one of the dozens of articles that loss mamas have written about what to say. Or ask here.
If you care about her at all you really should make contact. Apologise for the length of time it has taken, and be sincere. Don't make it about you or your guilt - it is nothing to the guilt she will be feeling. She is still very early in her journey, and she may not respond straight away, or at all. Do you know the baby's name? If so, use it. It's a powerful thing to remember the name and birthday of a baby or child who has died.
When my son was stillborn last year, I couldn't bear to see baby pictures all the time. I hid things on FB and only interacted with people when I could bear to do it. As a PP said, some days even breathing was hard. I was fortunate (in some ways) that I had DD to care for, as that gave me something to get up for each morning.
I lost a previously very good friend after DS died. Her little one was born around a month beforehand, and she was posting upwards of 20 photos of her son every single day. Yet, when she wrote to me over nine months later, her excuse for not being in contact at all (even to say sorry), was that she was too busy being a mummy to send a message. Don't do that - that was the last thing I needed to read. If she had been more honest and said that my baby dying had made her more afraid of hers dying too, I may have been more forgiving. I understand the fear of losing a child - I've lived through it.
