Aw, nakakagutom yan tignan talaga! Honest lang, a few of us tried simethicone at mixed results, some swear it helps with regular gas pains, pero para sa true colic, marami sa amin na parang hindi gaano effective eh, kaya nag-try kami ng iba. Kaya you're doing the right things na, biking, tummy massage, burping, yan talaga ang nakatulong mas marami sa experience ng kaibigan ko.
Since you're already doing so much, baka worth trying din ang gripe water if hindi pa, or checking if milk allergy could be part of it (common din sa 2 months). Pero honestly, best move is ask your pediatrician kung ano talaga ang nangyayari, kase sometimes what looks like colic ay lactose intolerance or reflux, at simethicone lang talaga hindi tutulungan dyan. Hoping mabilis ma-figure out kung ano ang causing the discomfort!
