I had this exact same thing with Sofia. It was then having a knock on effect on the rest of the day's feeding routine, even when I'd reduced the 5am feed down, so we did go ahead and resettle without the feed. We had a sippy cup on standby in case she needed a drink, but for the most part she resettled very quickly... After a couple of nights she would just wake up and do a little fuss then just chatter quietly for maybe for 10-20mins then went back off to sleep. All told it took about a week for her to naturally stretch out and sleep through. Good luck. xxx
