What is the reason behind a 2 month old baby gaining weight very slowly. My baby’s birth weight was 4.040 kgs and by today he has completed 2 months and is only 5.1 kg. He has gained only 500 gms per month.

A. He has gained 500 g in a month and 1 KG two months which is ideally good why do you think it’s a loop or low weight gain or gaining weight slowly it’s an appropriate weight gain every month 500 g is good enough
