DS is 5 days old and feeding well. He will feed for anything up to an hour on one side before dropping off to sleep. Sometimes that's it for a couple of hours, sometimes he wants to latch on again a couple of minutes later. How do I know when to swap sides? I know it's meant to be when there's no milk left on that side but usually I can still squeeze more out. So do I keep giving that side until there's none left? Mw said to offer the same side within the hour but if it's longer than that to offer the other one. What's best?
