YABU. She wanted to include her son in her wedding day. Her wedding was photographed for a magazine. Thus, her son was included in the photographs.
TBH, I find it distasteful that anyone feels the need to judge and comment on the way a grieving parent handles their grief. I have no freaking idea what this woman went through, the pain she feels. I have had four (early) MCs, and I almost lost my mind with the pain and grief and sense of loss. I can barely begin to imagine the horror of having your child inside you, watching your bump grow, feeling kicks, only to have that child die in your arms. So no, I don't think anyone gets to judge her for how she handles her grief, or lives her life without the child who should have been a part of it.
Death, particularly the death of a child, makes people uncomfortable. However, that does not mean that bereaved parents should hide away and shut up. It means that everyone else should learn to deal with it, and not make bereaved parents feel strange, or disturbed, or disgusting, or macabre for wanting to talk about, or indeed include, their beloved children. (Yes, I read the fecking comments on the shitty Daily Mail article, which is where I got all of those delightful adjectives from. I should have known better. Some of them truly destroyed my faith in humanity).
