Hay nako, first of all sending you a tight hug, mama, that was such a heavy loss and I can only imagine the worry you're carrying right now with this pregnancy. Yes, pwede na-gamit ang newborn clothes ng second baby mo, lalo na kung well-kept pa rin at walang damage; babies grow so fast anyway na parang basta lang suotin nila ang damit, and it's practical din na hindi na kailangan bumili ulit kung okay pa ang quality. A few of us mums sa circle namin, ginagamit namin ang mga damit from previous pregnancies na hindi nagamit, so totally normal yan, yung iba nag-donate lang ng some items to friends na may buwan na babae so kahit may rotation of use pa rin. The important thing is na ang clothes ay malinis, properly washed, and stored well, then you're good to go. Fingers crossed for a healthy delivery this time, mama, you've been so strong already.
