Hay, mama, oral thrush is something na kailangan talaga ng doctor check muna, hindi yan pwedeng i-self-treat kasi kailangan ng proper diagnosis at treatment plan para sa baby mo. Please take your 7-month-old to your pediatrician or nearest clinic as soon as you can, okay? A few of us moms went through something similar, at ang doc talaga ang nag-prescribe ng safe treatment, hindi kami nag-venture sa over-the-counter kasi it's his mouth and we wanted to be sure. Better safe than sorry, lalo na with babies pa! Goodluck, mama.
