A. dear Mum, for healthy weight gain, you can give foods like porridges (like rice, Ragi, wheat flour , moong dal and rice flour mix) , kheer then dal-rice with vegetables, veg khichadi, soft mashed fruits, curd. add ghee to baby's food. give 2 to 3 meals in a day and up to half katori every time. continue to breastfeed.
