I wonder how a couple of people in their late 40’s came to adopt two very small children.
While many adoption agencies give preference to younger couples, especially for infants, it could have been a private or international adoption.
In the early 90s my husband who was 41 at the time and I who was 32 looked into and tried, sadly unsuccessfully, to adopt as we couldnt have children of our own.
Some domestic adoption agencies including state agencies said my husband was either too old or that it would be more difficult for us. But at the time it was much easier to adopt from abroad and at the time a lot of adoptions by US couples were being made in Romania, Russia, Korea, Colombia, and the age of the adopted parents was not so much an issue as long as you had the money to pay and met income requirements and a very basic background check and in some cases such as Colombia, at least on parent had to travel there and stay sometimes for weeks or months while the adoption was finalized.
We knew a couple who adopted an infant from Korea when they were both in their mid-40s. And they didnt even have to travel, they met their adopted daughter at the airport when she arrived accompanied by someone from the international adoption agency.
We looked into private adoption and yes, sometimes the birth mother considers age, but not always.
Single people and even gays can adopt infants now days. How old was Madonna or Angelina Jolie when they last adopted?
