13 days old - cluster feeding not sleeping


My baby went from sleeping 3-4 hours during the day to now waking up every 2 hours starving day and night. Today she’d have a bottle and stay up for at least an hour after each one then be ready for another bottle. At night we can’t seem to get her settled. She’ll have a bottle and fall asleep so we’ll put her in her bassinet and she’s screaming 30 min later and we do this all over again. Except now she’s staying awake after each bottle and we’re not able to get any sleep!! Is this a growth spurt? I can’t figure this out I just know I’m very very tired.
