My little one is on 2.5/3 ounces every 3.5/4 hours....but I'd take the guidelines with a pinch of salt! Every baby is different! The calorie guidelines for adults never suited my eating habits so I don't see all babies sticking to theirs!
My 2 week old seems to have between 2 and 5 oz every 2-5 hours! It varies so much! I have no idea if she's having enough/too much or what but I'm just giving her what she wants every 3 hours in the day and whenever she wakes at night.
We had a the same problem, my little one was taking 2oz & all of a sudden wanting more and more from 2 weeks. Last week she was taking up to 40oz a day. Spoke to Health Visitor repeatedly who told us to keep feeding on demand & not switch to hungry baby. We are just shy of 6 weeks now and shes now taking 27oz. We're still feeding on demand but she just wants less. Baby will let you know & don't worry about over feeding.
My Lo is 3 weeks old and at about a week old he was having 3 oz every 3 hours. He then changed to 2oz every 2 hours & now hes on about 2.5 oz which is mostly every 2 hours, sometimes he does go longer.
