When Is the Right Time for the First Haircut?

The way this originally was explained to me, it is considered bad luck to cut a child's hair before they are a year old (Filipino superstitions).

Now that the boy is a year and some change, I think its time to give those golden locks a buzz, or at least a trim.  Mr A has been surprisingly resistant to the idea!  People have started mistaking our son for a girl, but not even a question of manhood could compel my darling husband to trim those curls!  I wonder why he's so anti-haircut?

I started putting his hair in ponytails in an attempt to drive home the reality of his androgony (the pink barrette was a bit overboard - but drastic times call for drastic measures) and Mr As only reply was that the baby looked like a "sumo wrestler!"

Hair grows back.  So do I cut it when Mr A is at work and let that be the final word or should I just let it grow because, in the end, its not that important to me anyway?   ..and that ponytail sure is cute.
