A six month old baby is ready for starting food other than formula milk. You can start by giving the baby some fresh fruit juice, mashed banana and thin moong dal khichri. You can give Narial pani, vegetable soup (stained). Remember that salt and sugar should be used sparingly. Start one thing at a time, see how the baby likes it. You can use full cream packaged milk, undiluted after boiling and removing the malai, with katori and spoon. Do not use bottles. Bottle feeding causes diarrhoea.
