Try singing or playing some calming music or white noise. I realized after a horrible night of fussiness that my son needs sound to sleep.

Put her on your chest.

Try a warm bath or put on some soft baby music it works for my baby all the time

Swaddling and bink worked for my son!

I sing to my cookie monster -_- he loves music and a good bassinet

I found a good swaddle reallllly helps. Also try a few different movements; bouncing, rocking, swaying..my second daughter was always fussy. Other than switching her to a sensitive formula, a firm swaddle, her binky, and bouncing always helped. Same with my niece :) hope that is of some help
