Mama, please see a doctor or go to the clinic today, lalo na may fever pa ang baby, hindi dapat mag-self diagnose tayo pagdating sa ganitong bagay, okay? The change in poop and constipation could be from the medicine, from the fever itself, or from something else entirely, so kailangan talaga i-check ng doctor para sigurado. A few of us mums have noticed na when babies are sick, lahat ng symptoms nila tumatagal, poop, appetite, lahat, pero walang dapat asahan without proper check-up. Bring the baby in and let the doc know about everything you've observed; they'll make sure baby's okay. Ingat!
