Aiyooo sayang, this sounds really stressful lah, your little one kena operate twice is not easy on the heart. You definitely need to follow up with your surgeon or paediatrician soon, because questions about hernia risk, wound care, and long-term management really kena consult the doctors who did the surgery, they know your baby's case best and boleh give you the exact care steps. I've got a few mum friends whose kids had tummy issues, and honestly, the doctors gave them step-by-step guidance on signs to watch for (like swelling, pain, infection at the scar), so please jangan worry sendiri, ask them lah to explain everything clearly, okay? Stay strong, mama!
