Yep pretty normal. DD is a 2 hourly (give or take) feeder during the day. Sometimes she just wants a quick drink 20 min after finishing a feed, sometimes she'll have a big long feed, sometimes it's just comfort. I'm just going with her patterns. They usually sort themselves out sooner or later! But, I do understand how you're feeling - there are days where I wouldn't mind a bit of a break! I just tell myself that it will all settle soon.
