Ay, singaw sa genital area ng bata is usually from diaper rash, yeast infection, or irritation from wet diapers, maraming reasons kaya importante talaga that you have it checked by the pediatrician agad para malaman kung ano talaga at ma-treat properly. Pwede ring mula sa diaper brand na irritating sa kanya or hindi siya dry enough, pero kailangan talaga ng doctor to rule out infections, lalo na if may discharge or it looks really red and painful.
