Ay, ang ubo with phlegm na tumatagal talaga nakaka-alala, mama! Since it's been almost 2 weeks na, I'd really suggest bringing your baby to the pediatrician para ma-check kung may underlying infection or kung kailangan ng specific treatment, kasi sometimes kahit walang fever, may need for antibiotics o other meds depending sa cause. A few of us moms noticed na ang lingering cough with phlegm ay kailangan talaga ng proper assessment para hindi lumala, at yung doc ay makikita agad kung ano talaga ang problema.
