How heartbreaking Adele. I would suggest you send her a card and possibly a gift for her babe (maybe a charm bead or something) saying that you heard about her baby and are incredibly sad for her. Let her know you would like to support her in any way you can and leave it at that for now. Contact her again in a few weeks (by facebook maybe, someway she is able to ignore you if she needs to) if you have not heard back and reitterate that you are there should she need you but you understand if she needs her space from you and your baby.

She may feel that it would be too hard to be around you right now. Equally she may feel abandoned by friends who don't know what to say so say nothing at all.
