❓My kid says they want to go vegetarian too — should I say yes?

Major nutrition organizations (like the Academy of Nutrition and Dietetics in the US) take the position that a well-planned vegetarian diet — including fully plant-based — is appropriate at every stage of childhood development, so 'should I say yes' is really more of a family decision than a medical red flag. If you do decide to support it, the key phrase is 'well-planned' — make sure there are reliable sources for total calories, protein, iron, zinc, calcium, B12, and vitamin D, and if needed, take your child to a pediatric nutrition clinic for an assessment and guidance, then track their growth curve regularly. You could also start with something like 'vegetarian a few days a week' and see how your child adjusts, rather than switching all at once — that gives both of you an adjustment period. At this age, a kid saying 'I want to do it too' is often about imitating and identifying with you, so you could turn this into a chance to learn a few tasty vegetarian dishes together — making it a bonding activity rather than just a restriction you're imposing.
