Everyone needs to find their equilibrium and their answers. Children are no exception. If you handle the situation well, likely, your child will never ask you /want to meet her biological parent. But don’t blame your upbringing if she does. It’s natural to wonder and to want to know. If your child brings it up, tell her that you will provide support to help her look for her biological parents if that’s what she wants. And that you will love her unconditionally no matter what she decides. In some cases, adoption may have happened from within the family or friends circle. In either case tell the child to think about it, and tell her that it may be difficult for her to look at the same people as she did before if they are known. And that it may cause conflict/confusion in her mind. It’s important to make sure that the child wants to know and understands that there are implications of knowing vs. not knowing. And then support her all the way through.
