Is this Frazzled Parent Syndrome or something requiring more thought?

We live in the Czech Republic, where open adoption is completely forbidden, so all we have is what is "reported." And in neither case was alcohol or drug exposure "reported." In my daughter's case it is less likely actually because the social worker I spoke to knew her birth mother long term and was very convinced that she was not into alcohol and said that she lived in a classical family household with several other small children that she cared for well and a long-term partner. Then again, with FASD, it doesn't take much. Supposedly, one time of a lot of alcohol (such as could happen if a person was very distressed by finding out that she was pregnant and didn't know what to do about it) is worse than an alcoholics low daily dose. So, one never knows and unless you are dealing with full-blown FAS, which I have seen first hand in a child I tutored, you can't really ever know for sure, even in school age.
