I am demand feeding, so I dont wake Claire if she is having a long sleep. I have done it a few times but then I find she takes a very long time to settle again if I do, so I dont wake her anymore. Claire does short sleeps and frequent shortish feeds (so annoying!) but it doesnt seem to work any other way for her. If I feel like I am about to explode from my breasts being so full, I just express and when I have done this, I have found she wakes soon after anyway, like she knows!! cheeky monkey!
