In my family this is so true. I have exactly the same bone structure and quirky, identifiying features that my dad has, and that his mum had. And by brother is the spit of my mum and her dad.
OH and I have been looking at the 3D scans of our son-to-be and he reckons everything is mine. I think it just looks like every other baby at the moment.
Just throwing it out there in a moment of boredom.
