I saw a scene from a movie, a woman (she was 30 I guess) found out that her parents wasn’t her real parents. Instead a friend to the family was the biological mother. I don’t know if this happens in the real life, I don’t mean international adoption, national. Me and my adoptive mom talked about these kinds of things and she said that there are some parents who only think about that they are afraid to loose the child is they tell the child the truth. But if you give your child/children love and make them feel safe, they will never leave them even if they have contact with the birth family
And I found it hard to understand adoptive parents who don’t tell the child/children about the country, family, culture. That won’t make the child wanna go back to the birth family !
