- Kashrus:
See Chapter 15 for the full details of this matter!
One of the most essential components of chinuch—both from a halachic and hashkafic perspective, as well as from a practical parenting standpoint—is ensuring that the food our children consume is kosher. More than that, it is vital that their food meet the highest possible standard of kashrut, beyond the minimum requirements of the letter of the law.
Not relying on Heterim for Kids to eat non-Kosher: As discussed in Chapters 1–2, and as will be examined in detail in the chapters dealing with the laws of kashrut as they relate to children, there are certain circumstances in which Halacha does not obligate a parent to intervene when a child is eating non-kosher food—such as when a child is below the age of chinuch, or when a child is ill and requires non‑standard food for health reasons. Nevertheless, despite these technical leniencies, the Poskim[1] emphasize that one should not rely on them in practice except where truly necessary. Likewise, the Poskim[2] rule that if one sees a child eating forbidden foods, it is fitting for anyone to intervene and separate the child from doing so, even though the Mitzvah of Chinuch is not upon them.
Eating only Mehadrin foods: The Poskim[3] rule that although from the strict letter of the law it is permitted for a child to consume mothers’ milk that derive from the breasts of a non‑Jewish woman, one should nevertheless refrain from doing so, as such nourishment can negatively affect a person’s character traits. From here we learn a fundamental principle: beyond the technical rules of what is halachically permitted or forbidden, there exists a broader and more encompassing responsibility—to raise children who are spiritually healthy. Just as parents strive to provide their children with the highest standard of physical nutrition and health, so too must they ensure the highest level of spiritual nourishment. This concern is especially critical in early childhood, when spiritual influences are absorbed deeply and can leave a lasting imprint. Spiritual harm incurred at a young age may have serious long‑term consequences later in life. In our generation, where the challenges of the secular world are far greater than in previous generations, this responsibility is more pressing than ever. Parents must therefore be meticulous not only to avoid feeding their children non‑kosher food, but even among kosher foods, to choose those that meet the highest standards and avoid relying on leniencies accepted by some organizations. Without entering into the broader discussion of whether hiddur mitzvah formally applies to children, it is clear that with respect to kashrut there is an overriding concern for the child’s spiritual wellbeing. For this reason, great care is warranted—an approach strongly emphasized in the Rebbe’s teachings, as expressed vividly in his letters on this subject.
From a letter of the Rebbe
Regarding the question of how to conduct oneself with respect to foods that are not fully mehudar in kashrut, when such foods may seemingly increase a child’s appetite: The concept of hiddur in food, as explained in many places, relates not only to the fulfillment of the mitzvah itself. Rather, since all food eventually becomes blood and flesh within the body, which is bound to the soul, the level of kashrut and refinement of food directly affects the character traits and moral qualities of the person who consumes it.
Accordingly, any additional level of hiddur, refinement, and purity in one’s food should be viewed as an enhancement in the formation, improvement, and refinement of one’s character and middos. If this principle applies to adults, it applies all the more so to children, whose characters are still in the process of being formed. For this reason, there is great significance to the direction in which children are guided in this matter.
In light of the above, it is clear to me that since this does not involve, G‑d forbid, a situation upon which health is truly dependent, but rather concerns an enhancement of taste or appetite, one should not compromise on the hiddur of food. Certainly, other methods and alternatives can be found to strengthen a child’s appetite and health, without doing so at the expense of kashrut and its standards.

👉 Eight Practical Guidelines for Educating Children in Kashrus and Mehadrin Hashgachas
- Teaching Children Which Kashrut Standards the Home Relies Upon
Parents should explicitly teach their children which kashrus organizations, standards, and certifications are accepted in their home. This helps the child develop clarity, consistency, and personal responsibility in kashrus, and prevents confusion or accidental transgression when eating outside the home.
- Teaching Kashrut Sensitivity When Eating by Others
It is essential for parents to educate children which kashrus organizations they may rely upon when eating as guests, and which they may not. This guidance should be given with emphasis on sensitivity and derech eretz, so that children learn to uphold their family’s standards without embarrassing or judging others who follow different standards. Such education trains the child to combine fidelity to halacha with respect for other Jews, preventing shame, conflict, or arrogance, and fostering mature and compassionate observance.
- Treat Kashrut as Spiritual Nutrition, Not Only Law
Help children understand—by tone and attitude more than words—that kosher food nourishes the soul just as healthy food nourishes the body.
- Maintain a Consistently Mehudar Home Environment
Children absorb norms through exposure. A home that consistently uses reliable, mehudar supervision sets a natural standard, reducing confusion and avoiding the need for frequent explanations or exceptions. Thus, it is best to keep to set Kashrus Hashgachas permitted within the home.
- Explain When Relying on Leniencies
When halachic leniencies may apply (e.g., young age or necessary food), parents should explain the matter to their children as otherwise it may weaken their sensitivity to kashrut.
- Model Kashrut Integrity through Parental Behavior
Children learn more from what parents eat than what parents say. Consistent adult behavior—especially outside the home—teaches that kashrut standards are principled, not situational.
- Prepare Children in Advance for Outside Food Situations
Before visiting others or events, gently explain what the family eats and why, so the child is not put on the spot or made to feel deprived or embarrassed. - Avoid Turning Kashrut into a Source of Conflict or Control
The goal is sensitivity, not resistance. Firm standards should be paired with warmth, patience, and alternatives, so that kashrut is associated with care—not frustration. Unfortunately, there are situations in which kashrut is experienced by children not as a value, but as a means of control—where food becomes a battleground over what they may or may not eat. Children are often sensitive to this dynamic, and when kashrut is presented as rigid or restrictive without flexibility, it can breed resentment. In such cases, when children grow older and gain independence, they may react by rejecting or circumventing the very values their parents sought to instill. For this reason, sound chinuch requires balance. It is both proper and necessary for a home to be conducted on a high standard of mehadrin kashrut, establishing a clear and principled baseline. At the same time, when children are outside the home—such as when eating by others or traveling—it is important to provide them with acceptable halachic options that remain fully kosher, even if they are not the family’s preferred standard. This approach prevents kashrut from being experienced as oppressive and instead presents it as thoughtful and livable. For example, in Eretz Yisrael, many families eat exclusively under the supervision of Badatz Yerushalayim at home, yet nevertheless allow their children to rely on other recognized and halachically valid hechsherim when visiting others or when only such options are available. When guided properly and sensitively, this teaches children loyalty to halacha together with derech eretz, realism, and inner commitment—rather than rebellion.
🌿Example 1 – The Klein Family (High Standard at Home, Flexibility Outside):
The Klein family maintains a home that eats exclusively Badatz‑supervised food, without exceptions. Their children grow up knowing that this is the family’s preferred standard and that at home they do not compromise. However, from a young age, Mr. and Mrs. Klein calmly explain to their children that when they are guests—at a simcha, at relatives’ homes, or when traveling—they may eat food that is under other reliable and fully kosher hashgachos, even though these are not what the family uses at home. The children are taught which hechsherim they may rely upon and to do so respectfully and discreetly, without questioning or embarrassing their hosts. As a result, the children grow up valuing high kashrus standards while also developing derech eretz, flexibility, and healthy ownership of Yiddishkeit—without resentment.
🌿Example 2 – The Weiss Family (Preventing Kashrus from Becoming Control):
Mrs. Weiss noticed that her teenage son was beginning to feel frustrated when he could not find food outside the home that met the family’s very stringent standards. Rather than insisting on an all‑or‑nothing approach, the Weiss parents sat down with him and explained the difference between their home Kashrus levels and what is halachically acceptable when eating elsewhere. They clarified which leniencies he could rely on when necessary and emphasized that the goal of kashrus is kedushah, not control. At the same time, they taught him to be sensitive and respectful toward Jews who follow different standards. This conversation helped the child feel trusted and respected, and instead of rebelling, he internalized kashrus as a thoughtful and meaningful part of avodas Hashem.

Even when they are rebuked directly, they are not receptive to moral instruction. And who is greater for us than Elisha ben Avuyah? For he did not come to that path because of any later deed of his own, but rather because his mother, who was pregnant with him, passed by a place where food was being cooked for idolatry. She smelled it and felt a need to eat from it, and that substance permeated him like the venom of a snake.”
Time‑Dependent Prohibitions: The Achronim have discussed whether this negative effect applies also to permitted foods that become prohibited due to time-related restrictions, such as chametz on Passover, eating on Yom Kippur, and eating matzah on the day before Passover. [See Darkei Teshuvah 81:90; Ketzos Hashulchan 147 footnote 4] From the words of the Gemara in Yoma (82b), which discusses a pregnant woman who smelled food on Yom Kippur, it is evident that this category is also included. [Arugas Habosem O.C. 138] Nevertheless, it is certainly forbidden to be stringent in a situation involving even a possible danger to life, and the ruling must be determined according to the judgment of the halachic authority in each case. However, allowing a minor to eat before kiddush or havdalah is clearly more lenient according to all opinions, since this prohibition is merely a rabbinic safeguard enacted out of respect for the sanctity of the day.
