Hello..my baby is not gaining much weight She is 7 months old and weight is just 6.4 only so What should I do to gain weight??

A. Soak a cup of ragi in two cups of water for a few hours. Drain and grind the soaked ragi by adding a little water, as required, to extract the juice. This juice can then be mixed with milk and cooked with a little jaggery or sugar, added for taste. Adjust the consistency as required by adding more milk.https://parenting.firstcry.com/articles/amazing-health-benefits-of-ragi-for-babies/
