I might be BU but I can't shake my head around how a mother can say this.
I befriended a mother in the school playground a couple of years ago - our DDs are friends - and she had her last baby 8 months ago, a boy. She has 6 children in total now four boys, two girls. Oldest is around 14 I believe. She's Caucasian with blue eyes and is married to a man of Hispanic descent and all of her children have beautiful brown eyes except her youngest who has her blue eyes. I recently met up with her and another friend for some coffee and other friend commented on her baby's blue eyes, saying he's mummy's mini.
She responded with "They are definitely mine, 6 children and all I asked is for one of them to have blue eyes. None of them until my DS" and she similarly said a couple of months ago "I waited 14 years to get my blue-eyed baby"
I probably know I am BU but I've had 2 miscarriages in the past and my DD is my only child although I would have loved more. Surely, the only thing you ask is for your baby to be healthy? Not on what you hope they'll have appearance-wise? 
I'm friends with her on FB as well, and all of her photos are of baby and one or two with her youngest DD and her baby brother.
