Teach Your Children

Abaye said:
Wherever an adult would be obligated to perform a Mitzvah under Biblical Law, There is also an obligation to train a minor under Rabbinic law. Wherever an Adult would not be obligated to perform a Mitzvah under Biblical Law, a minor also would not be subjected to the obligation of training under Rabbinic law.

(In the case of today's daf, if an Adult is not obligated to bring an offerning due to a disqualification. There would be no Rabbinic obligation to train the child if the child would also be subjected to the disqualification, even if the Child could become qualified by the time they would reach adulthood)

- Chagigah 6a

Good Shabbos!
