Answer: i guess your baby age is 2 years not 2.5 months as you mentioned. the milk or milk products are very important for babies not just the fat but they are great source of calcium .so you can try mixing in other food items like add cheese in khichdi while cooking. cook in butter, add milk in shakes or smoothies, you can add curd in fruit salads, mix them well ..prepare oats in milk with Apple in it. oats hide the milk contents. give Apple kheer ice cream.. frozen yogurt. slowly when the taste build you can back to normal feed.
