Adopting.org has posted an excellent article on how adoption will affect your child at different developmental stages. Though every child moves through the developmental stages at a different pace, having a general understanding of what to expect will help you recognize where your child is at and how best to respond.

"Whether children are adopted as infants or when they are older, whether they are healthy or have physical or psychological problems, their adoption is bound to influence their development. You need to understand how and why."

The article is a bit long, as it goes into detail about each of the many developmental stages, but the information is solid and important.
