Aww don't worry, darah O memang slightly higher risk tapi bukan must-have punya thing lah, many of my mum friends dengan O blood type pun babies dia okay je! The best thing is frequent breastfeeding (or feeding la) from the start, even every 2-3 hours, sebab that helps baby pass meconium faster and reduces bilirubin buildup. Also make sure baby dapat enough sun exposure in the morning (window sill boleh la, atau keluar untuk 10-15 mins), lepas tu kena monitor baby closely for any yellowing and do the heel prick screening that hospitals offer, kalau caught early, it's very manageable je. Tapi honestly best to discuss with your gynae or paediatrician specifically about your O blood situation, they can advise better based on your history.
