i have a 16 week girl who drinks 9 oz approx 5 hours apart. if i try to feed her earlier she will outright refuse and cry. i have been told that this amount is too much and the time is too long inbetween. what does your baby take? she was 9lb 11oz at birth and is now 17lb 4oz. what was your baby at birth and what do they weigh now? just so i can get some comparison
