I believe that if the baby goes from X percentile to a lower percentile then its "falling off the curve" for that specific baby. I dont know what the previous weights were exactly do I cant say why. However I do know she is put on 1/4 of an inch for a whole month. That is ok ?
Anyway - I think there is onemore problem -she wants to nurse only once 4-5 hrs. I keep trying to nurse her and she keeps crawling away and only comes back when she wants to.
