Aww, first time mom worries talaga yan! Sa diarrhea, ang importante ay hydration, water lang is okay, but ORS (oral rehydration solution) like Hydrite or even homemade salt-sugar water is better kasi may electrolytes na nakakatulong talaga. A few of us moms swear by coconut water din, sobrang gentle sa tummy at hydrating. Pero if it's your baby or kung prolonged na ang diarrhea, kailangan mo talaga mag-check with your pedia para sigurado na okay lang, lalo na kung may iba pang signs like fever o blood sa dumi.
