Your kid wants to go vegan. Should you let them?

Hi readers! Shayla Love here, science journalist and longtime fan of Your Mileage May Vary. I’m honored to be subbing for Sigal Samuel while she’s out on parental leave. I’m diving into your questions as a way to help understand human nature and our choices through multiple lenses: philosophical, psychological, and beyond. Please send in any emotional, body/brain, sociological, perceptual, or other kind of life quandaries you might have.

My child, age 9, has decided she’s vegan. Neither of her parents are even vegetarian — we’re “free range chicken/grass fed beef” types. She has learned about veganism from friends at school, and seems to have come to her position more or less on her own. I want to encourage her ethical choices, but her mother and I agree that children should be introduced to new foods and flavors at this age. She has no allergies or intolerances that we know of. I worry that making accommodations for her dietary restriction may lead to a lifetime of picky eating, even if hers is a reasonable and ethical approa

When I was around your daughter’s age, I went to Hawaii with my parents. One night, we ate dinner on the beach, and we watched as a pig was dug up from an underground steam oven. I was horrified to see its face and nose; most of the meat I had eaten so far in my life didn’t resemble the animal it came from. A few years later, I became a vegetarian, and then in my 20s, a vegan.

Have a question you want answered in the next Your Mileage May Vary column?

I share this story to reveal my slight bias in answering your question, but also my understanding of the ethical awakening your daughter might be experiencing. As you figure out how to talk to your child about what she decides to eat, we can at least table discussing the pros and cons of veganism itself. Instead, you should think about what amount of autonomy your child should have, and whether the moral decision-making she wants to engage in matches with her current stage of development.

People don’t turn 18 and then suddenly start engaging morally with the world. As we grow up, we try to understand right and wrong in fits and spurts. Lawrence Kohlberg, a 20th-century American psychologist, is best known for attempting to track a person’s moral development throughout their life.

Kohlberg presented people with hypothetical dilemmas in order to come up with six moral stages. In one example, he asked people of different ages about a dying woman who could be cured by a drug that was cheap to make, but that a manufacturer was charging an exorbitant fee for. The woman’s husband ends up stealing the drug. Is that right or wrong?

Obsessing about being a good person can backfire. There’s a better way.

Kohlberg observed that in answering questions like this, young children have what he called a “preconventional morality”: Their notions of right and wrong are dictated by what their parents think, and the avoidance of punishment when breaking those rules. For instance, the main reason not to throw your dinner on the ground or hit your brother was to avoid consequences from parents, not a feeling that there’s something wrong about that action.
