It's interesting the arguments put forward by those who think she's guilty are very much a repeat of all the things that don't prove anything such as the notes, not crying at the right time, wanting to cuddle her cat etc.
The hard facts are when these babies died they had postmortems that all found causes of death which were nothing to do with air embolism/over feeding or any of the other theories concocted by Dewi Evans. This was accepted and was fact.
The police blindly went along with Dewi's theories and built a case to fit, dismissing any expert who challenged it (Jane Hutton). These theories have since been discounted as nonsense and even impossible by anyone who knows what they're talking about. It's like the people who still believe she's guilty have forgotten the actual facts of the case.
If the same trial happened again with the exact same incorrect evidence and theories presented by the prosecution and the same defence team another jury would probably find her guilty again. Her defence team did a terrible job by not calling any experts and the police did a terrible job by only having the one expert who wasn't a neonatal expert and was allowed to mark his own homework!
As others have said, people should be very worried about this. It could clearly happen to anyone.
