I totally understand how scary it feels when the doctors flag something so early, especially when you are a first-time mum and everything is already so overwhelming. When my second child had a result flagged from the newborn screening, I remember just staring at the paper not knowing what to ask or where to even start. The most important thing right now is to follow up closely with the PD or the specialist they refer you to, because they will guide you on the next steps based on your baby's specific results. Please do not wait or try to figure this out alone, bring your baby in as soon as you can and write down all your questions beforehand so you do not forget anything in the moment. You are already doing the right thing by reaching out, and I hope you get clear answers and support very soon.
