I was born in 1951 into a middle class (professional father, stay at home mother) and it's occurred to me that I've never seen any baby photos of me or my siblings! There are studio portraits of us from toddler stage onward and I've seen holiday photos, but none of us as babies.
If you were born at that sort of time does your family album include baby photos? (Our birth certificates indicate we weren't adopted, by the way). Was it just not the usual thing to do?
I've got another 'keen'... Ouch!
