24 weeks and waking up at night to feed

Jena

My baby has been waking at like 2am and 5am to breast feed for like 10 minutes and falls asleep. But then wakes up as soon I lay her down. She has been like this for about 2 weeks. I am not sure if its a phase. I am a first time mom. Before this she was sleeping from 10 to 6 would wake up to eat and go back to sleep till 8. She usually naps naps about 3 hours. I'm not sure what to do. Any advice??
