Chinuch Hora'ah of the Day:
Some think that because their child is sent to a frum school, a school where the children learn only limmudei kodesh, they have fulfilled their obligation. Parents must know that although a Torah institution is very important in order for the child to hold onto his chinuch, the Torah atmosphere in the home must be palpable. Even if the child comes home only to eat and sleep, he must sense the aura of Torah in the home. This palpable aura in the home is created when his father, the businessman, grabs every free moment to say a pasuk from the Torah, or a maamar of our chachomim; when the child sees sefarim all around the home, and when in everyday conversations, the mother brings up points and ideas from Tze’ena Ure’ena, Kitzur Shulchan Aruch, and other Torah sources.
