My son has colic and reflux, and I rock him, and pat his back like I’m trying to burp him or I pat his butt, also if your baby cries at night a lot it helps to sit on the edge of your bed and bounce up and down along with patting your baby’s back or if you’re really tired you can lay down with your baby on your chest and pat his back. You can also give him a paci, if he uses pacis, and pat his back while he’s sucking to help soothe him or if you breastfeed let him do comfort sucks while patting his back.
