Hi mama! Usually 2-3 hours lang between feeds if 6oz, pero depende talaga sa baby, some babies digest faster, some slower, kaya baka 1.5 to 2 hours na lang if 4oz lang. Pero honestly, if pakiramdam mo humihina na talaga ang suck niya at you're worried about weight gain or milk intake, better check with your pedia to rule out any concerns, pwede lang normal developmental stage, pero mas okay na ma-assess ng doctor para sure. Siguro din if gusto mo mas malalaki ang portions, gradually increase to see how baby responds. Mama friends ko nag-adjust din ng amount based sa baby's cues, so don't hesitate to track feeding times and amounts para makita mo ang pattern.
