My LO was born 6lbs 8oz he lost weight with in the first few days, as normal, and got down to 6lbs flat. He had some latching issues so I start pumping to bottle feed. He started off eating 2oz every 2-3hrs and then went to 3oz when he was 3wks. Now he is almost 6wks old and drinks 4-5oz every 3.5-4hrs. Also he is 10lbs 4oz now and if I try to give him anything less he will cry and stay fussy until he gets more. So am I really overfeeding him?
