Aw mama, ganyan din ang aming first born around that age kaya alam ko ang struggle, walang tulog para sa inyo both! Besides ang massage at manzanilla, try mo rin ang burping nang matagal during feeds, sometimes they swallow air habang nag-latch, at check din if your latch is tight enough kasi kung loose, mas maraming air papasok. A few of us mums also swear by changing positions while feeding, try upright o football hold para mas madaling lumabas ang gas naturally. But honestly, since it's been a few days palang at sobrang severe, kailangan mo ring i-checkup ng doctor ang baby once the rain stops para ma-rule out kung may milk allergy or reflux na involved, especially pag purely breastfed pa lang siya, sometimes our diet (dairy, caffeine, gassy foods) affect them too. Hang in there, this phase does pass!
