Speculating - obviously - but could she have been looking them up on FB to see photos of the babies? We’ve heard she may have had a photo of twins after they’d passed on her phone (still to be clarified) so could this have been something she was actively checking for?
Quite a few of my friends who’ve lost babies, either through stillbirth or shortly after birth will at times set their profile picture or cover photo to a picture of the baby after it has passed (not a graphic photo, but one of the baby being held, swaddled or in a moses basket etc). Especially around anniversaries, birthdays, Christmas, wave of light etc - times when you would reflect and share memories. Could she have been looking for this?
Disclaimer: we lost my nephew at 7 months old, so I do have a slightly higher than average number of friends who have experienced stillbirth or death of a baby/young child through baby loss support. I’m not suggesting all bereaved parents share pictures of their babies who have died or that I’ve just got loads of friends who have been through it like it’s a common occurrence. But those friends do tend to share the pictures at important times in their babies life.
