I have a colleague who bought a baby from Colombia, via an agency and I didn't hear about it until all the "congrats" were given in a small meeting. I felt sick and numb thinking about the poor baby and mother and what circumstances she must be in to do that.
I think the fourth trimester is not spoken about enough either - that mother-baby bubble that lasted (in my case) for the first four months of my daughter's life was very healing for me, as I suffered incredibly bad post-natal anxiety, almost to the point of mild psychosis as I was plagued with mental images of her coming to harm.
My daughter would scream as soon as she was put down or held by anyone else, but having her strapped to my chest in a sling for the majority of the day made us both feel safe and secure.
