My son 1 month and 20 days old. Birth weight 2935 gms now 4300 gms. I am still confused whether my baby is having enough breastmilk or not. He ask for feed every 1 and half hour when he is awake but at night generally wake up only two times till morning. Does feedings last for 40 to 45 min is low milk supply sign? Why does he is hungry just in 1 n half hour? However my both breasts leaks milk most of the times.
