My MIL works in public health as well. The stories I’ve heard man. She’s also been the only one to try to talk my and my wife out of fostering (we have two kids of our own, have room in our house and hearts for another but don’t really want to do the whole pregnancy and newborn thing again. We’re still on the fence). Her reasoning is that we won’t be able to handle the heartbreak and having to be part of a lot of these stories.
