I love the idea of giving books for babies!
Pat the Bunny is a classic.
I understand what you mean about most miscarriages happening in the first trimester and it being painful to have baby supplies and no baby... but I look at it this way: Babies who die before birth are often forgotten by everyone but the parents. Having a reminder helps the parents to feel that their baby was
real and that other people recognize that.
A gift that is a sad reminder at first might end up being a treasured memento of their child who had such a brief life.
But now that I've bummed out myself and others... let me move to happier thoughts... a certificate for a prenatal massage!
I would have loved one of those!
