Frances Cappuccini, 30, had wanted a Caesarean birth at Pembury Hospital, Kent, in 2012, but she was allegedly persuaded to allow labour to progress before needing an emergency C-section.
The mum died from a haemorrhage just hours after her son Giacomo was delivered, leaving her husband, Tom, 33, devastated.
Teacher Mrs Cappuccini, from West Malling, Kent, was nicknamed 'Mrs Coffee' by pupils and she was described by colleagues as 'bubbly and a brilliant'.
Doctors Nadeem Azeez, 52, formerly of Tunbridge Wells, and Errol Cornish, 67, from Bromley, have now been charged with gross negligence manslaughter.
An arrest warrant has been issued for Azeez, who is thought to be in Pakistan.
The CPS has also been authorised to charge the Maidstone and Tunbridge Wells NHS Trust with corporate manslaughter.
The first hearing in the case is due to take place at Sevenoaks Magistrates' Court in Kent on May 1.
Phillip Hunter, headteacher of the 200 pupil primary school, said at the time of her death: "Frankie did her teacher training with us nine years ago and stayed on afterwards.
"She was a bubbly, enthusiastic and positive person and on top of all a brilliant teacher. She was a friend and a colleague to us. The community is shattered to learn of her death."
The Maidstone and Tunbridge Wells NHS Trust said it was unable to comment on the case.
