- "How much did she (he) cost?"

There are numerous fees and expenses associated with adoption, just as there are expenses associated with giving birth.  The above question implies that a baby has been purchased, and is generally considered offensive.  If you are considering adoption, ask if there is a convenient time to call and discuss adoption.  If you're not considering adoption and are just curious, it's really none of your business. 

- "Are they real sisters (brothers)?"

If you have adopted more than one adopted child people want to know, "Are they really siblings?"  A family built through adoption is no less a family than one built biologically.  Siblings through adoption are no less siblings than those through biology. 

- "Why didn't you adopt from this country? We have needy kids here!" 

 A child is a child, and every child needs parents and a home.   Domestic adoption can be a minefield.  Some families are willing to navigate that, some are not.  Some adoptive parents feel "called" into the adoption process, often to specific places.  Personally, I went where I knew my children were.   If you have a strong sense of call towards the children of America who are in need of parents and homes, then you should search your heart and do what you can for those children.   

- "He/she is so lucky to have you!"

Every child deserves loving parents and a safe home.  Hopefully, every adopted child has one.  Children are always a blessing.  It's the parents who are the lucky ones!

* Lastly, never make any disparaging remarks about either the birth country or the birth parents.
