I struggle to understand why someone would choose a vegan diet for a baby, to be honest. It introduces clear and well documented health risks, such as vitamin B12 and iron deficiency, and requires supplementation and medical supervision to ensure the child is growing and developing properly. That alone suggests it isn’t a straightforward or natural choice for an infant.
From personal observation, I’ve yet to meet a vegan who appears genuinely healthy in the long term. Many seem pale, fatigued, or nutritionally depleted, even at a young age. While that’s anecdotal, it does raise questions about how easy it really is to meet nutritional needs on a vegan diet.
There’s also the issue of choice. A baby has no say in this decision, yet it imposes significant dietary restrictions based on parental beliefs, similar in some ways, to how belief systems like religion are passed on. Given the potential health implications, I find it difficult to justify making such a restrictive choice on behalf of a child who cannot consent.
Beyond health, there are social consequences. School, nursery, and parties can already be challenging for children, and restrictive diets often lead to exclusion, even when others try to be accommodating. I’ve seen children left without food at parties simply because suitable options ran out. Allergies are unavoidable and already difficult enough to manage; choosing a restrictive diet when there’s no medical need seems to add unnecessary hardship for the child.
For these reasons, it makes far more sense to me to allow children to eat a varied diet while they are growing, and then let them decide for themselves later, as teenagers or adults, whether they want to follow a vegan diet. At that point, they can understand the nutritional responsibilities involved and make an informed choice.
