Have you ever heard an Yiddish Word "Naches"?
Per Ariela Pelaia the definition of the word is: Naches is a Yiddish word that means "pride" or "joy." Typically naches refers to the pride or joy that a child brings a parent. For instance, when a child is born people will often say to the new parents "May [your son or daughter] bring you naches." The "ch" is pronounced gutturally - so it's not "ch" as in "cheese" but rather "ch" as in "Bach" (the composer).

EDIT: I got few comments about how cute and beautiful the youngest girl in a blue shirt is. Please note, the youngest child is a BOY, not a girl, with most beautiful curls I've ever seen. Jewish boys are getting their first haircut when they turn 3 and this special haircutting ceremony is called Upsherin. This session was happening a week before the Upsherin, so of course capturing these curls was a must!
