How many ounces is your LO eating at 8 weeks? (Breast milk and formula — she gets about 50/50 in her bottles) And how frequently are they hungry?

My girl is a chunky monkey and was eating about 5-6oz every 3hrs or so but she’s been getting belly aches so I think she just doesn’t know when she’s full and is over eating?

Was going to try to knock her bottles down to 4oz today, but she’s so was so fussy after her bottle and nothing else seemed wrong so I topped her off by nursing her and she was fine.
