Fussy Baby at two months plus

Hi community! My baby is about 2month 10days old, at material time. She is really fussy and me and my wife find it hard to take care of her. When she cries, we tried all methods to soothe her crying. Sometimes, she also is very fussy while feeding. Is this a phase? Is there anything my wife and I can do about it? Thank you! From a concerned parent.
