How much breast milk is needed for a 2 month old baby of 4.15 kg i mean how much ml as im pumping and giving him feed

A. See every child has its own appetite there is no to denial to it so for first 30 days we say about 30 ML would be good than 60 for another 30 days like from the age of 31 to 60 days now when your child complete age of 60 days then you can slowly start giving somewhere around 90ML to a child in one go
