My baby is 5.5 months old and on formula milk.. he hardly consumes 550ml -600ml per day. Is this sufficient? His weight is 6.3 kg

A. As per the current age the weight seems quite good rest you can check as per the birthweight your child should have gained a minimum of 500 g in a month so evaluate on that basis if you see that this birth rate is well within that thing that is good enough
