There is a misconception about how at risk premature babies are - my sister is a neonatal specialist, primarily dealing in substance addicted newborns. I caution that I try and follow the stuff that she tells me but I have the attention span and intellect of a mudskipper.
However, prem. babies have a very, very good survival rate in the UK. I'll be certain to speak with her about this case when next catch up, but I have a real impression that the number of deaths should have been alerting to a number of professionals.
