Newborn's first haircut

And what are the reasons

stupidity. just don't do it man. let the child grow a bit. you will hear all kinds of make-the-arm-fit-the-sleeve arguments that it's more hygeinic and what not but at the end of the day it's just some primitive tradition people have carried on on the name of religion. I smack myself couple of times every time I remember how my family made me do it and how stupid it really is. wait at least couple of months.
