Adopting an older child

My husband and I have decided to adopt an older child. We are 24, have a daughter of our own (almost 2), and have had a stillborn and a miscarriage. I grew up around my best friends family who fostered and adopted all ages and children (7 total) and have a great view of it (also have seen the ugly side, but you get that with any child). We are more than blessed financially, the child brought into our home would be in private school, active in our church (unless they so choose otherwise), and a member of our families just as any birth child. We are very nervous about pursuing a 10 year old boy. We are anticipating the “how old are you” calculations (10 and 24, meaning people will think I was a teen mom), the “is he your real son” comments (YES, but don’t touch him he’s just as real and loved in the flesh as the baby I pushed out, lol), and “he doesn’t look like you” because my husband is 100% Italian and the boy is fair skinned, haired, and eyed. Luckily, I usually don’t care what people think, but my heart breaks for the questions he will have to answer. I never want him to feel overlooked, loved less, or anything of the sort. My husband and I both have amazing jobs, with the flexibility of going on school field trips, sporting events, etc. Has anyone been in this situation before and have words of wisdom/encouragement?
