If your pediatrician approves, the "milk ladder" approach is often used to reintroduce dairy by starting with highly processed options, such as baked goods (like cupcakes or biscuits), before moving to cooked dairy like yogurt, and finally fresh dairy. Start with very small quantities (e.g., 1/4 tsp) and monitor for symptoms like rashes or tummy pain for several days before increasing. If breastfeeding, some pediatricians recommend introducing these items into the mother's diet first to see how the baby reacts through breast milk.
