Could this have happened to you?

I recently saw an article on tv about how two Czech babies were mixed up at birth and ended up with the wrong mothers. They are both 10 months old and now have to be returned to their "birth" mother. My kids are mixed race (I am black and my husband is white) and would never need a dna test to prove they were our kids. Although they are not white skinned luckily they have his eyes, teeth, two slightly webbed toes. Our daughter has her dad's nose and our son's nose is just like mine. They had our features from the very first day they were born..
