How much sleep

How much sleep does a baby need at night. My baby is 2 months I was curious how much sleep should baby should be getting at night. She wakes from a nap usually around 7:30ish will get feed,bath,book and will fall asleep around 9ish. She wakes 2-3times at night ever 3-4 hours some nights ever 2 hours. So it’s like midnight and between 4:30/5 for a feeding. Is that enough sleep for little one or should I be trying her to bed a little earlier.
