Formula is typically based on cow’s milk. Human milk has higher sugar (lactose) content than cow’s milk. The nutrition for building baby cows and baby humans is different enough that infants shouldn’t just be fed a balance of nutrients that works for other mammals. Some cultures use this or other mixtures like sugar water out of necessity, but it’s not a good idea if you can avoid it. Around one year, once the child is eating other foods, is when they start recommending adding cow’s milk.
