When my bub was 1 week old, she'd take 80ml of breastmilk from a bottle in 1 feed. She's now 7 weeks old, and we're lucky if she'll take 25mL. My IL's babysat her last week for about 4 hours and during that time she drank about 75mL. When she only drinks small amounts, she's still content and will go to sleep easily. I think I may have read somewhere that some breastfed babies will hold out until they can drink straight from the breast, is this true? I just don't like to think that she's hungry!
