The difference with Rajiv's child is that the Hb was above 10 until recently. If the Hb has dropped below 9 already, there would be no question about transfusing, but it has only now dropped below 10. If it continues to drop, there will be no point in avoiding transfusion, but it should be below the point where it would be after transfusion if transfusions are to begin. This may happen quite soon, but from the beginning, this case has defied the predictions.
