My daughter 5 weeks old has been diagnosed with 4 mm VSD , PFO after ECHO reports. He weight is increasing gradually and takes bottle feed normally but struggles in Mother's feed. At birth she was 2.8 kg now at around 3.8 kg. Please advice next course of action. Will it need surgery? Some docs in my hometown suggest to see a pediatric cardiologist whereas some say it will heal on its own.
