advice for teen mom with colic baby?

emani

hi i’m a new teen mom with my first baby girl! i believe she’s suffering from colic because a couple times a week around 6, 7 pm she would cry non stop, her crying often sounding like she needs to poop.. her diaper would be changed, she’s nice and fed, not hot at all, i’m rocking her and she’ll still be crying :( any advice to help sooth colic? she’s also 4 weeks old! one month on the 28th ❤️
