What is your baby’s weight now? There’s a formula to calculate the amount to be given to baby based on his weight. You can refer to this website. https://www.omnicalculator.com/health/babys-milk-intake I’m giving 100ml of bm to my LO (4 weeks old) every 3hours.
TMC recommended multiple newborn weights with 150ml, dividing the no. of feeds per day.
Increase 5-10ml each time, if he spits up that’s his limit.
