Sayang, I can hear how worried you are, and it's completely understandable. But this is really something you need to discuss in detail with your baby's specialist, they know your little one's full medical picture and can answer these specific questions about prognosis and recovery timelines properly. Don't rely on online answers for this, okay? What I can say is, a few of us mum friends have kids with ongoing health conditions, and honestly, the doctors will guide you step by step, blood tests, scans, medication adjustments. It's a journey, not something that happens overnight, tapi ada hope with proper care. For now, focus on keeping all those appointments (MRI, CT scan, blood work) and write down any questions you have so you can ask the doctor directly about whether the thyroxine will help long-term and what to expect. Your baby is in good hands being monitored. Stay strong, mama.
