Dear if baby has completed 6 months nd 7 month has started u can start semi solids. As u can give dal water soup, rice water soup ,mashed banana ,sooji wit milk too nd slowly slowly start solids too .nd a big no for cow milk .as it's not safe for under 1 year babies .as babies kidneys r immature they cannot digest cow milk before 1 year..cow's milk lacks the proper amounts of iron, vitamin C, and other nutrients that infants need .so avoid it . Give only breast milk or formula milk untill babybxompleted 1 year...take care
