We are two white parents who adopted a black child internationally. He is still a toddler so I can't share our experiences of him growing up. Interestingly our LA has quite a few transracial adopters where it is obvious they are not biologically related.
There is lots of good advice above. We had a lot of prep on transracial adoption in the UK. The evidence we were quoted is that about 10% are left with identity problems. Many of the children have a rough ride with identity esp in the teen years - but they can get there if you support them in the right way. Other transracially adopted adults have told me it was really important for them to know other transracial adopters.
Society has changed a lot and there are a lot more multiracial families around. I noted someone at toddler group who is trying up teach their birth child 4 languages and that still omitted one language from the parent's heritage.
I found our visibility as a family a hard gig identity wise (for me) at first. Once I took ownership of it and walked the walk, we got less comments and looks. I also got better at responding. This is important for your child to see.
The other thing is that nothing is black and white (scuse pun). We get more questions in our highly diverse area than a white middle class one where people are too polite to ask or else maybe they're more familiar with adoption. I wonder sometimes if our area is too black and all the black kids are just gonna hang with those of other black families. My friend's biracial kids live in a very white area in the middle of nowhere and go to an ultra expensive private school but there are kids of Nigerian heritage there.
This is very early days for us but my sense is it is about finding what is right for your child. If it means moving in the future for his wellbeing then we will do it. We have lived in his birth country and can educate him about his culture - but we can't make him BE from that country. I think we can only show him his culture so he can help himself if he wishes to when he is older.
Incidentally, my son has a very unusual name. I found it very awkward at first but did not want to change it because it is part of his identity. Again, I have learned just to embrace and say it confidently and without any kind of apology that it's hard to spell or whatever. TBH I have heard some names from the young trendy brigade around here that I find it hard to get my head around.
Our son gets lots of positive attention from strangers saying he is cute. As for hair patting, he pats them right back! If the match feels right in other ways, then do some reading about what you are getting into but it can be done.
