“It1 is a Jewish custom not to shave or cut a boy’s hair until he is three years old.

“The first haircut (Yid.: opsherenish) is a major Jewish custom, the main point of which is training the child to leave his peyos (‘sidelocks’) uncut.2 It is usual from this day on to be particular to accustom him to wear a tallis katan (tzitzis), and to recite the morning blessings, the Grace After Meals and the bedtime prayers.”
