Thanks to everyone who has offered their advice/ knowledge whether personal or otherwise.
DS has one day of steroids left and has seen a little bit of improvement, but in the online research that I have done I do know that any progress can be up and down.
Some of the online stories have I read the palsy has lasted weeks to months, the worst being a question posted by a mum of a 9 month old who had had it since birth and no change at all in that time.
