Makhanas, also known as fox nuts, are one of the healthiest meals for babies and can be introduced to them once they reach the age of six months. To make Makhana Kheer for babies, first roast the makhana in ghee till crispy, then finely ground it. Bring the milk to a boil, then stir in the powder. Cook the kheer for 8-10 minutes with cardamom powder. Don't make thick and creamy kheer because it will be difficult for them to digest. Make sure to cool before serving.
