So sorry your children have FASD as I’ve heard it is difficult to manage. I adopted domestically and most of the pediatricians I spoke to told me to accept a potential birth mother who did any drug before one who admitted to excessive alcohol. I was very surprised by that. I don’t think FASD is just an issue for international adoption as I’ve seen it with people who adopted domestically too. It’s sad.
I know my children were examined for specific facial distinctions (like a smooth philtrum and thin upper lip) - do yours not display these? Is is not in all children who are FASD.
Good luck to you and your family!
