A baby probiotic is worth a try. Google it as lots of forums suggests that it’s helpful
I've heard a few success stories with taking ur baby to a chiropractor when diagnosed with colic Also Second the eliminating dairy for a couple weeks. They thought my nephew had colic when it was a dairy issue
We used camomile tea to help with my daughter’s colic
If you breastfeed or formula feed you can try eliminating dairy from you diet for 2-4weeks. It may be cmpa, or soy allergy. Otherwise bicycle legs, belly rubs. Earphones and lots of walking outside
