Uy, mama, please take baby to the doctor or pedia na para ma-check nang mabuti, lalo na kung mahigit isang linggo na! Hindi ako dapat mag-diagnose, pero importante talaga na makita ng doctor yan. A few of us mums have experienced unusual skin changes sa babies, at ang best talaga is get it checked right away para sure. Could be something simple, pero mas peace of mind kapag confirmed na ng professional, di ba? Let me know how it goes, okay? Sending love!
