You could try a 3.5 hour EASY, it may be she is ready feed wise. Smaller more frequent feeds suit most refluxers but mine both went to 4 hour feeds before the 4 month mark - they would just refuse to eat sooner. The only problem as such is that you won't get a true EASY because they won't be able to do the A time for the longer EASY. What you will find is that it becomes something like EASAES until the A time catches up. This does work, just watch that you don't feed to sleep when E is right before S.
If she ate at 1.50 I would see if you can get her to 3.5 hours after that, she should be hungry by then. If she does keep having small feeds just watch that she has wet nappies and isn't showing any signs of dehydration. I would still consider looking into the reflux, her feeding patterns are very similar to my DD when she was bad. The poor feeding was her main symptom, she napped well, slept well at night was/is the haapiest smiliest baby but the feeds just weren't right. How does your DD behave when she is feeding?
What flow teat are you on - have you tried a faster flow?
