Colic / gas gripe water , white noise , just walking around with baby show them different environments.. distract them as best you can.. tummy time , if you breastfeed you may need to change your diet ... cut out dairy or certain things like beans
My daughter was also colic but my mom told me to buy a soft peppermint ball n but it in a five oc bottle fill it up to 3 with water n let the peppermint fade a away in the water give it to your baby till he/she doesnt want anymore after that theyll be better then ever it worked for my girls
Have you tried a different formula? Idk if ur breastfeeding or not. Things that helped my first was to cradle the baby over your forearm(baby face down) head towards your inner elbow, legs straddling forearm. It helps relieve tummy gas. Swaddling, static noise(like running a vacuum, a fan, a heartbeat sound player,radio static. Gripe water, or wrapping baby against your bare chest. I know its hard so remember to take a breather. I hope your able to find something to soothe your lil onr. Take care
