Sayang, ini memang kena follow up dengan doctor, jangan delay, boleh? Kidney calcification kat babies ni perlu monitoring proper supaya tau perkembangan, so kena jump straight to paediatrician atau nephrologist yang handle cases macam ni. A few of us mums ada experience baby dengan findings macam ni during scans, and the doctors always explain it better in person, sometimes it's nothing serious, tapi kena confirm dan follow the plan mereka. Jangan stress dulu, tapi do push for the next appointment ya. Sending you strength!
