Thanks Jess. After reading your post I've cut back to 150 mls and I think he's chucking a little less. He always cries when the feed is finished now - as soon as I try to burp him. I then chuck the dummy in and he's usually OK after that. Until today he was still feeding at the same intervals as before but he's now wanting a drink quite a bit earlier. I guess I'll just have to see how it goes.
