7 month old girl baby weight gain food and fruits pls tell me.. IQ foods pls tell

A. There is no such definition of weight gain food or IQ increasing food you should just give all the food to the child all the fruits and vegetables Khichdi porridge you can give varieties of food that you can prepare out of ragi oats and Suji you can give lots and lots of liquids to the child which are going to be healthy and just avoid giving junk and sugary food to the child as that’s not good for brain IQ or even for the growth and immunity of your child
