I don’t look like my parents and this was always something that bothered me as a child. I look nothing like my brother either. Features and hair colour are totally different. I do have blue eyes like my dad, but blue eyes aren’t that uncommon anyway.
Usually if you don’t look like your parents, you resemble another family member e.g. grandparent, cousins, aunties etc. but I don’t see it.
I’m starting to get seriously concerned that maybe they picked up the wrong baby. If that was a possibility in the late 80s when I was born.
