Haiyah, memang scary kan kalau nampak ada sign yang different kat anak kita, a few of my mum friends dalam group juga ada pergi through this, so tau how stressful it feels. First thing is kena bring him to the doctor (paediatrician or GP lah) cepat-cepat, jangan delay, because they can refer you to a specialist like a developmental paediatrician or child psychologist untuk proper assessment; early detection really does make a difference la. Jangan stress dulu sampai ada diagnosis, tapi do act on it seriously, mana ada salah pergi check awal kan, better safe than sorry. Your child will need your support either way, so just take it one step at a time, okay?
