Hi Kiran, the more u will feed the baby, the more milk you would get. If the baby is peeing atleast 6 times in a day, he is getting enough milk. Have milk inducing things, like garlic, jeera, oats, lauki, daliya, Masoor ki dal, fennel seeds etc, have shatavari granules in milk. Have atleast 4 litres of water per day. If still nothing works, then start formula with doctor's suggestion. Do not give cow milk before one year of age. And avoid bottles if possible, feed by bowl and spoon.
