My 6 month son has suddenly reduced milk intake. Presently, he is given cerelac and banana shake in morning and evening respectively. But recently i noticed that he haa reduced his formula milk intake. Earlier, he used to take 5-6 ounces per feed for 3-4 times a day. Now he takes 3-4 ounces that too with a lot of effort at my end. I need to know the reason behind this behaviour. I started him on solids when he was 4.5 months old.
