Refusing bottles!

Hi is anyone else’s LO rejecting their usual bottles? I suspect it’s the leap but my LO is now rejecting her once-a-day bottle of 120ml (4oz) breastmilk during the day. I’m hoping it’s just the leap. Even when I leave my apt so she can’t smell me she will still hold out, maybe drink an oz just to tide over until I’m home to nurse. We also have upgraded to the medium flow nipple. We know it’s not the bottle because she was taking it fine a few weeks ago since birth. Anyone else?
