I don't know. But I did lol. I just lost all expectations that anything else was normal. If that makes sense. DS was EXACTLY the same. Every hour on the hour. And he didn't sleep overnight and I coped with that too (most of the time ). I think I was just so ecstatic to be feeding him myself as I didn't with DD1. But don't feel bad if it annoys the crap out of you. Maybe give yourself a list of things to do in those 30 minute breaks? That's what I did. And instead of big blocks of achievements I would achieve things gradually throughout my day. Whatever gets you through, there are no rules AND drink LOTS. Can you rest your eyes and feed in bed while she feeds?
