On 9 March, the Royal Glamorgan hospital in Llantrisant stopped providing consultant-led maternity care - instead offering only midwife-led care.
Consultant-led care is now based at Prince Charles Hospital in Merthyr Tydfil. These changes were initially part of the "2014 South Wales Programme" which were plans to secure the future of four hospital services in South Wales and South Powys.
Concerns were raised that those needing consultant-led care would have to travel further, or that women who experienced complications while giving birth at the Royal Glamorgan Hospital would then have to be transferred.
The most recent concerns come against the backdrop of a major review of maternity services in the Cwm Taf Morganwwg health board area.
The health board was quick to cite difficulties with staffing and launched an external review. A separate external review, to be carried out by the Royal College of Obstetricians and Gynaecologists, was also launched.
The external review is expected to be made public in the coming weeks, but external investigators gathering evidence found areas needing 'immediate' action.
The health board maintains the changes are the right thing to do to ensure enough staff can provide safe care - something that's again being questioned.
