My son is turning 6 months in next 10 days. He has been showing interest in what we are eating so we started very little amount of fruit( banana, apple), oats, dal water(less than a spoon even) just to give him a taste of food. From last 2-3 days, he is asking for more. How much food should be given? Is it ok to give him 2 different foods , eg. banana and oats as two different meals 1 spoon each daily?
