The milk ladder is a structured way to reintroduce dairy into a child's diet by starting with foods where milk is heavily baked (like cakes or biscuits), moving to cooked forms (like paneer in curries), and finally progressing to plain yogurt and eventually milk. It is common practice to start this process by having the breastfeeding mother consume these items first to see if the baby reacts through breast milk before offering them directly to the child. Always consult your pediatrician before starting, and maintain a gap of about one week between new steps to monitor for any reactions, increasing the quantity gradually as tolerated.
