Bersin kat bayi yang baru lahir tu normal je, don't worry! Sistem hidung dia masih cleansing diri dari amniotic fluid dan debris dari dalam rahim, so the sneezing is actually a reflex yang bagus. A few of my mum friends juga experience this with their newborns at that age, dan semua fine-fine je. Tapi kalau accompany dengan batuk yang persistent, demam, atau breathing difficulties, better check with your paediatrician just to be sure. At 19 days old, you're still in the hyper-vigilant phase (totally normal!), so if you're concerned, just call your doc, they won't mind
