I am just heartbroken for her. It is her third. I am pregnant with my third and there would have been the exact same age gap between our second and third. There is nine weeks between our two ds2s. Her other sil is also pregnant. It's just unspeakably awful.
We don't live in the same country so I can't offer much in the way of practical help but I want to do something to let her know how much we are thinking of her. It is so unfair.
we lost our first at 22 weeks, we got given a rose for the garden which was lovely. any cards or kind words or flowers were really helpful, makes you feel like everyone gets how horrendous a thing it is and that they are feeling it alongside you.
My dear friend went through a similar dreadful loss. I dedicated a tree through the woodland trust (and wrote a letter too, obviously). You can choose which woods, though there's nothing attached to a particular tree, you just know that one of the trees has been dedicated (and will not be dedicated to anyone else)
