Fussy 3month old

My baby had been sleeping through the night(from 10pm- 9am) only eating about one or two times per night( she dream feeds). Recently she has been fussing every two hours at night and I try to pat her butt and put white noise but she wouldn't fall asleep until I put my boob in her mouth to feed her. Is she really hungry? Is this a growth spurt, it has happened consecutively three nights now.
