Please Help 🤔🤔

When i pumped , i only get 90ml or 100ml combined from both sides that to in 30mins .But when my son, who is 4months old nurse , he only nurse for 5mins from one side only . Will he get that much of milk in 5min from one side? Which took me half an hour to get from both sides ?

Is he getting enough ?

I also give him formula 2-3 times a day.

He only eats 90ml or 100ml per 2hr-3hr.
