I’m so tired and fed up.

Every single night, baby wakes up after not even 5 minutes of me putting her down. She’s 10 weeks old, I thought she would sleep better by now. She had started sleeping 4/5 hours at 6 weeks but suddenly stopped after a week. I’m tired and fed up. I can’t pump to increase my supply, I cant spend time with my husband, we barely see each other. When does it get better?
