My son is now eight months and one day old and weighed 2.780 kilograms when he was born. How much should he weigh now?

A. Should be 6700 g on the minimum side as the expectation of weight gain is somewhere around 500 g in a month so if you calculated it should be 4 kg more but in general standard if we talk about it generally should be somewhere around 7 1/2 to 8 kg
