Carl's surgery has been postponed

Yesterday around noon we arrived here in Johannesburg, I flew and Helen travelled in the ambulance with Carl.
The hospital we are at houses the Walter Sisulu centre for peadiatric cardiology for Africa, so he can't get much better care than here.
After about an hour the paediatric cardiologist came to examine Carl with ultrasound.
Her conclusion (a bit different from the doctors in Durban) was that surgery is absolutely necessary, and if he was a bit bigger it should have been done immediately. Since he is very small the risks would be too great to do the surgery now, and since he seems to be doing ok at the moment, it would be better to wait until he grows some more, ideally wait for 6 months.
So they are keeping him here for 4-5 days for observation, and then they will reassess what to do. It could be that he stays here longer, or that he will go back to Durban and then come back here later.
