As everyone says, salt and sugar should not be given till a year. But can I introduce rock salt in his meal? Also, can I use dates syrup as a sweetner in his meal?

Hi Let your baby be over six months and then you can add little salt yes black salt won't be bad rather it is considered good for digestion. You can use dates syrup as a sweeter but make sure there are no preservatives in it. Make you own home made sweetner and avoid all packed food from market or which have preservatives.
