Bydd yr ail gam datblygu yn cynyddu capasiti'r cyfleusterau yng Nglangwili. Bydd mwy o gotiau dibyniaeth fawr, cotiau gofal arbennig, ac ystafelloedd i rieni aros dros nos, yn ogystal â mwy o ystafelloedd geni, theatrau llawdriniaethau, a chilfannau dadebru. Hefyd mae cynlluniau ar gyfer lleoedd parcio ychwanegol i 59 o geir.
The second phase of developments will increase the capacity of the facilities at Glangwili. This will include more high dependency cots, special care cots and parent overnight stay rooms, as well as increase the number of birthing rooms, operating theatres and resuscitation bays. Plans are also in place for an additional 59 car parking spaces.
