I would think it is very difficult to go through life not knowing the factsof one’s biological family.
I’m sure the level of interest is different for all adoptees, however medical information and history would be one of the reasons. Could you imagine going to throw doctor and saying idk when being screened?
There is also a piece missing of connectiveness or closure or for some who have not been shared details of thier adoption, even if they have the most loving adoptive family, and sharing these details may help with that.
If an older adoptee is searching for thier biololical parents though, discreetness and the expectation of them not wanting contact must be understood before hand.
Depending on the circumstance too, I would think it is an act of love and sacrifice to desire a better life for a baby, and that should be communicated to the child as early as possible. It is not that they are unwanted, it’s because of life situations and timing that makes raising them not ideal.
God bless all in the adoption triad, adoptees, adoptive parents and biological parents.
