Adoption from Ethiopia

Adoption from Ethiopia? Adoption in general? My knowledge on these subjecam trying to become informed so that when my daughter and son-in-;law bring home my first grandbaby from Ethiopia I will be prepared. I would imagine when a daughter and her husband are expecting a baby from her tummy (uterus, to be medically correct) a grandma just sort of falls into the role. The baby grows, the baby kicks, the baby demands to be born and walla, there it is! But when a daughter and her husband are expecting a baby from Ethiopia, the journey is very different. Time lines are unknown. I am the type of grandma in waiting who would want to buy many things for the baby, but when is the proper time to start this purchasingts is minimal, but I ? For fear of jinxing things, I don't want to start that until they are at least on an official waiting list. Many, many people are adopting from Ethiopia. Will there be enough babies for all who are waiting for these precious little ones? It is just my nature to create these problems where there probably aren't any real problems to begin with.
I also know that there are many unknowns about a pregnancy. Babies can die in utero, babies can be born with defects and babies can develop diseases shortly after birth. So there is uncertainty even in a baby growing in a daughter. That fact gives me much comfort at this point. Adoption vs. Natural childbirth (probably the wrong terminology, but I am still learning, as I said) there are many unknowns and many uncertainties in both. More similiar than I thought...
