About using millets as first foods at 6 months: Should I just use the powders and cook them like porridge? We generally have them in roti form – can we just grind the rotis with milk and give?

Don’t mix ragi with milk, esp for infants. The iron in each food is better absorbed if they are digested separately. Simply make the ragi porridge with plain water and add nothing else – no salt, no sugar. In a few months when your baby is able to chew he can enjoy the ragi rotis just like you.
