I think at 4-8 weeks the normal is 2-4oz but my doc always say to feed on demand! My bb is 11.2 pounds at 4.5 weeks old 🫶🏼
Mine is 7 weeks and same. Takes different amounts but HV said that's OK as long as still gaining weight and overall intake over 24 hrs averages ok
Mine finishes a 5oz bottle of expressed milk in the evening with husband whilst I put my toddler to bed. He’s EBF at all other times and gaining weight nicely. He was born at 6 lb 15 oz and is currently 10 lb 13 oz
My baby is 4.5 weeks and drinks 2-3oz on most feeds, sometimes even 4-5 if he’s really hungry lol
