Ang skin color ng newborns talaga ay nagbabago during the first few weeks, kaya normal lang yan! May iba't ibang shade depende sa genetics at kung gaano siya exposed sa init, pero usually umiiwas ito by 1-2 months. That said, kung worried ka talaga o parang may unusual rash o discoloration, better check with your pedia para ma-rule out lang any concerns, mas comfortable ka naman pag sigurado, di ba?
