It wasn't unusual not to cut a little boy's hair until age 3 or 4. A lot of people still follow this tradition.
My son's first haircut was 3, but my coworker cut her son's hair when he was like 6 months old because
it was lopsided.
Also, not too long ago, baby and toddler boys sometimes wore gowns, dresses, and short pants up to a certain age, depending on their family's status and wealth. This fashion trend might have been followed into the 50s if this child was, indeed, from a prominent family with old values, where there may have been an old school matriarch in charge of the nursery.
It's similar to how the royals still follow the short pants tradition for their little boys.
So to say he may have been raised as a girl and his hair had just been cut could indicate the investigators
may have forgotten how little boys used to be dressed and groomed by the well do do, depending on his age. Under age 6, then there's a good chance he wasn't raised as a girl, but as a typcial toddler boy from a tradition-following, well to do family.
OT: Is anyone else having issues with lag on this site? It's freezing & lagging big time on me, like it's bogged down.
