Wa'alaikumassalam! Aww, I understand your worry, mama. Tapi untuk benjolan kat kepala baby, especially berhubung dengan labour, kena betul-betul check dengan paediatrician atau doctor, jangan tunda, okay? They need to examine baby in person to make sure semua okay. A few of my mum friends went through similar situations, and doctor mereka boleh explain better apa jenis benjolan and the right way forward. Banyak cases actually resolve on their own, tapi kena expert check dulu. Jangan risau, just book an appointment ASAP, ya!
