Am I depriving my baby of a feed??

Buffy
Please someone help me out with this I EBF my 9.5 week old baby and the time between his night feeds are getting longer but occasionally he will wake up a couple of hours after going to sleep and start to cry if I give him his dummy it usually settles him back to sleep, my question is, is he actually hungry and I'm sending him back to sleep or would he carry on crying?? Also is he too young to sleep through without feeds should I be waking him? Please respond! Tia
