Anak, I know it's scary, pero please contact your pediatrician or go to the hospital na para ma-check ang baby, hindi dapat maghintay pa lalo with newborns. At 8 days old, ang pooping pattern ay really important, at kung may 24 hours na walang output, kailangan ng doctor's eyes talaga. A few of us mums had similar worries, and the doctors were so reassuring once we got checked, minsan it's nothing, pero better safe than sorry with newborns, 'no? Call your OB or baby's pedia right now, ha?
