My older one went through a period like this and later on we found out he was having colic. Not sure about your baby, you may wanna try:
- swaddling as it mimics the womb (this works well for my 2nd one and he gets up easily if not swaddled)
- play some white noises to soothe her (seems like it only works for some babies)
- check if she's too hot or too cold
- could she have been used to being held in adult's arm to sleep?
Hope this helps and may you find a solution soon!
