The above isn't always true, but if you didn't investigate the agency deeply you should assume it is. This is why international adoptions are so hard, many counties have caught on and given up on giving the few kids who do need real homes help.
You have to be kidding me. Do you know how many kids are literal orphans in sub-saharan Africa?
Meanwhile, we literally sell babies with impunity which we euphemistically call "surrogacy."
Moving is hard on children, not so much on infants, much more so on teens.
But the idea that parents ought to be prohibited from moving is a truly radical idea.
Eventually they adopted a 100% healthy local child after 5-6 years of legal nightmare as it's pretty complex navigate through all requirements plus wait your turn.
I definitely respect people who adopt, but they risk of just adopting someone else's problem is too high for me.
