4mo hunger cues

What are the hunger cues for a 4mo now? My baby will make this frustrated "mmmmm" sound when she needs her diaper changed, hungry or tired. So everyday is trial n error. And half the time after heating ebm, she doesn't want the bottle. But neither does she look tired nor soiled her diaper On top of that, she gets v distracted by sights or sounds.

Any advice would be good to make each passing day an easier one. Most nights i really feel damn defeated and tonight is one of those nights i feel like breaking down
