Adui, memang susah kan nak cari tempat yang trustworthy untuk jual barang baby! Aku try Lazada Preloved dulu, and honestly quite okay, aku dapat feedback cepat and buyers cepat pulak. A few of my mum friends also swear by Facebook Marketplace groups (ada specific groups for baby items je), sometimes lebih cepat sold sebab local pickup. Boleh also try Shopee Pre-Owned section or Carousell (since u mentioned it), I know u already know but some sellers report Carousell action faster than Mudah. Good luck with the sale, at least barang baby tu usually move quite fast compared to other items!
