Great topic! I am passionate about adoption. We brought home a 3 year-old from Korea 8 months ago. I have wanted for years to adopt an older child. We had already adopted an infant from Korea a year and a half earlier. It is a wonderful way to build a family! We love our kids very much.
There are so many resources now, that make the transition easier. The internet, books, agencies, other adoptive families online...without all that, this would have been even more difficult.
One thing to remember with older child adoptions: it takes a while to truly feel attached to the child, and that is normal. If you've had friends over who have children, and they messed with your stuff or pulled your dog's tail, it gives you about the same feeling. They don't FEEL like yours for a while. So if you go into it with low expectations about the time it takes to FEEL the love, it is better. And it does come! Love, after all, is a choice, no matter what the movies say. ;-)
