As to the WT's view?
The WT didn't really committ for or against, always saying it was the parents decision. But........
Many in the congregations would talk in a disparaging way about us making such a poor decision in wanting to adopt when we are so close to the new order. (I was a Pioneering Elder at the time and taught at the Pioneer School) We adopted our girl in 1991, we are now in our 50's.
If we followed the mature reasoning of that day, we would not have had a lovely daughter to share our lives with.
But it was that talk that lead to our leaving the WT. The talk became so bad that few in our KH would accept her, to the point of treating this 1-2 year old poorly. And these were the Elders, Pioneers, the supposed strong ones. An Elder even used the scripture with me, that in Israel, a bastard child was not to be accepted. (He is now a CO)
Bringing it up with our then current CO, and how discouraged we were, he acknowledged the talk was true, but we should not hold it against them, as they meant well. Ugh!
In the end, all went well, as this episode opened our eyes to the fallacy that this is God's loving organization. We raised our daughter out of it and she is a very nice young lady who is starting college soon.
I asked her recently if she had any recollection of the KH? She said very little, but that the meetings were very boring and people were so mean to her.
