Sleep regression please help 1yr old hasn't been sleeping well

My daughter has slept through the night since she was 1 month old (unless she was sick) but not all of a sudden at 13months old she is waking up 2-3 times a night. I go in rub her back pat her butt etc to soothe her and out her back to sleep sometimes I have to rock her for over a hour or sometimes my husband has to take her and sleep with her in the living room chair or else she won't go back to sleep. Idk what has happened....there is nothing wrong with her its like she just doesn't want to sleep or she feels the need to be held while sleeping or she won't sleep. Nothing has changed and she isn't sick or teething currently. She has the same stuff she always a has a had nice machine dark room soothing fan humidifier etc...

Please help me out give me tip or help me understand whats going on because this isn't my baby's norm.

Thanks
