Ay, anak, please take baby to the doctor or nearest clinic agad-agad, especially since 3 days na at sipon with ubo, kailangan talaga ng proper check dahil napakababy pa lang niya at 2 months palang.
I know it's scary, mama, pero better safe than sorry talaga with newborns and cough, they need to listen to baby's lungs properly. Hindi pwedeng pagsugalan lang. Keep breastfeeding though, because that's the best proteksyon you can give her right now, lalo na kung may sipon siya! Lakas mo na, mommy, go to the doctor.
