Responsa על סוכה 83:10

Q. A court is not enjoined to restrain a child from eating forbidden food (Yeb. 114a; Git. 55a; Shabb. 121a). Is a father obliged to restrain his child?
A. A father is enjoined to train his son in the performance of the Mitzvoth. Lack of disapproval on the part of the father means approval. Therefore, a father must restrain his child from eating forbidden food, if eaten in his presence. This law, however, applies to the father, but not to the mother.

Q. Slaughtering of an animal on the Sabbath is punishable by stoning, while eating forbidden meat involves only the trespassing of a negative commandment. Why, then, are we permitted to slaughter an animal on the Sabbath for the benefit of the critically ill, when feeding them forbidden meat would involve a lesser deviation from the Law?
A. Work done on the Sabbath for the benefit of the critically ill is considered as if done on a week-day, thus involving no infringement of the law.
