Normal?

My baby girl will be 3 weeks tomorrow. She’s drinking like crazy. Anyone else’s LO do this? She will eat 2.5-3oz then have a good 1hour wake window then eat another 1-1.5oz the fall asleep she does this quite often during the day and night. Sometimes she even goes to sleep and wakes up an hourish later for more… Normal? Growth spurt?? Picture of my little Turkey
