i would just feed when she gets up. many babies don't take 2hr naps +/or A time varies. you may find her naps shorten a bit as her awareness grows or you may be very lucky and have 2hr naps for a long time... unless the naps get so long that she is going 4 1/2 - 5 hrs between feeds i woudl not worry too much ...
also when they are older babies drop milk feeds and there is more of a juggling with milk, solids and nap times - you move beyond 4 hr EASY to a bkfst/lunch/dinner scenario...
