I am completely open with my children about their own adoptions. However I believe it is their information to share as they wish not mine.
They do not wish me to tell people at toddler group , school etc that they are adopted, so I do not. I would never dream of telling any of their information to anyone, even close friends or family. There are many cases where people fall out years later and the information is used against the child.
For us, there is a difference between something being secret and private .
Eg it's not a secret that DH have sex but our sexual relationship is private. I would only discuss it on a " need to know " basis eg with my GP. To do otherwise would be disrespectful to my DH. It's not because I am ashamed or embarrassed of the fact that we have sex. Indeed, I'm very happy with our sex life. It's just not anyone's else business.
For is it's the same with adoption. I feel strongly that if parents want to share, they should discuss their OWN personal information, not their child's .
I have rarely been asked direct questions about the birth of the adopted children. If women are swopping labour horror stories, they might ask " was x a normal delivery or a section? " or something similar. So I just answer truthfully. If they press for more details, I just say something like
" oh that a very long story,you don't want to hear it "
Or whatever people in your area say when they mean " I don't want to talk about it "
It's actually very rare for people to ask directly. Mostly it's just a conversation opener so they can tell their stories.
If you decided to tell casual aquaintances about your children's background, you need to be prepared for a lot of questions. Eg why were they taken away? Was it drugs/drink? Were they in prison ?
You also need to know that people think that all adopted toddler and children are deaf, so they will feel free to say very inappropriate things in front of them eg
They are so lucky to have good parents like you now
She's so pretty, I can't understand why anyone could give her away
I hope they appreciate what you have done for them
You are such a wonderful person. I could never love a child who wasn't my own
I was once asked by a nurse ( while my child was in hospital, so her adoption was on the medical record ) " was her real mother a prostitute? "
. I have no idea where she got that from or why she thought it was ok to ask. It wasn't in any way relevant to the medical problem . And It was in front of the child .
