Hi Angeline, If baby is gaining weight well and wetting enough diapers this should be fine. Are you breastfeeding (direct latching or expressed breastmilk) or formulae feeding? If you’re DL then ideally you would be feeding on demand. The 3 hour guide is pertaining to the maintenance of your milk supply which is supported by frequent milk removals. You could do a pump in between to build your stash and that should help. On an average, milk should be removed from the breast at least once every 3 hours.
