800gm increase in one month. is it good? baby on BM only

A. It’s actually very good look I would like to clarify this thing that a minimum weight gain should be 500 g in a month right and the maximum that it can stretch in a month should be not more than 1 kg kilo kilogram gain 800 g in a month which is ideally better than the minimum weight gain so it is a very justified weight gain for the child
