For adoptive parents, it is important to decide whether you want your child to know about his past or not. If you decide to tell him his past, learn the correct way to do that, and if you don't want to reveal the truth to him, avoid saying a few things which may shatter his life. Also, never use the word 'real' for addressing the child's biological parents, because there is nothing like real and unreal when it comes to parenting.
