You need not give a baby salt until one year of age. If you do want to introduce salt, limit it to less than 1 gram per day for babies older than six months. However, it is better to avoid salt for babies under one year of age. Giving sugar to infants less than one year of age is not recommended. Baby foods do not require added sugars. You can use natural sugar substitutes like fruit puree, date syrup or honey. Even fruit juices given to babies must be diluted to reduce the sugar content.
