Alamak, tu normal je when babies cry hard, blood vessels kat kepala jadi prominent sebab tekanan darah naik bila menangis kuat-kuat, so urat-urat tu kelihatan lebih jelas je. Tapi kalau urat tu nampak sangat besar, bengkak, atau baby nampak sakit even bukan time nangis, better check with your paediatrician just in case, okay? A few of my mum friends notice itu kat babies mereka jugak tapi hilang balik once the crying stops, so mostly nothing to worry about lah, tapi better safe than sorry.
