Aww, mama, I totally understand the worry, lahat tayo nag-aalala pagkakita ng kahit ano sa baby natin! Please bring baby to the pedia or even go to the nearest clinic/hospital today para ma-check agad, hindi dapat maghintay lalo na lang na 6 days old pa lang siya, kailangan peace of mind mo at ng baby. A few of us moms here had lumps or swelling after birth (sometimes from delivery mismo, sometimes from other things), pero talaga, baby's age and the softness of it, kailangan tingnan ng doctor para ma-rule out kung ano exactly. Hindi mo dapat mag-alala mag-check, mas okay na alam ninyo agad, diba? Keep us posted, momsh!
