Mama, please have your daughter checked by a pediatrician right away, okay? Any lumps or bumps sa suso ng baby need professional eyes, and it's better to be sure. Hindi ako makakapagsabi kung normal yan based lang sa hormones mo, kaya kailangan talaga ng doctor para ma-examine siya properly at ma-rule out kung ano ang nangyayari. You're doing the right thing by reaching out at noticing these things, that's good mothering. Kaya mo, at siguradong makaktulong ang doctor sa inyo. Let me know after the checkup, ha?
