I need sleep

Did anyone else baby stop sleeping at 5 months ? She use to be a great sleeper at night now she wakes up every 2-3 hrs, she still takes good naps , at night she either wakes up hungry or fussy like she needs help going back to sleep or sometimes she’s just talking and I’ll rock her back to sleep, I never play with her or talk to her I make it strictly bed time. I just don’t know how she went from sleeping 9-5am straight to waking up all through the night , any suggestions?
