Sounds like colic. try applying oil and massage her tummy and back after diaper change. Try to burp after every feed. Do some tummy time. Probably might want to do some cycling motion on her leg when she is awake(watch on youtube for the exercise) If u are bottle feeding probably u might want to change it, i have people recommending hegen or pigeon. U can try one at time. See which one works for the baby. If not i would suggest u to visit a PD.
