6oz every feed for 16 week old

Lauren • Had my sweet girl 02/22/20 - 5 weeks early due to rare genetic disorder💗 Had my handsome man 09/30/22 - 3 weeks early due to low birth weight💙

Does that seem like enough? My daughter is fed by a G tube, so it’s hard to tell if she’s still hungry since she doesn’t bottle feed primarily. Im always worried she’s not eating enough. I told her pediatrician and we’re still waiting on a referral to a dietician, so I was just wondering for in the mean time.

(She sleeps through the night so she’s only eating 6oz every 3-5 hours throughout the day)
