Aww, colic talaga ang kukulit, I remember those nights with my firstborn, parang concert ang bahay natin haha! Walang instant cure pero what really helped kami is doing skin-to-skin contact, gentle rocking, at making sure wala siyang swallowed air during feeds (burp siya well). Tried din kami ng different holding positions and sometimes just white noise or soft music calmed her down, plus yung warm compress on her tummy seemed to help. But honestly, best to check with your pedia kasi baka may other reason din behind the crying, they might suggest formula changes or other tips na specific sa baby mo. Hang in there, mama, it does get better after the first few weeks!
