Yn ogystal â chaniatáu ar gyfer yr hyblygrwydd hwn, mae'r canllawiau wedi cael eu diwygio ar ôl gwrando ar adborht gan fenywod a theuluoedd ac ymgynghori â Penaethiaid Bydwreigiaeth a gwasanaethau Sonograffeg a Radiograffeg.Bydd ymweliadau mewn gwasanaethau mamolaeth bellach yn seiliedig ar asesu risg gan y byrddau iechyd. Bydd hyn yn cymryd i ystyriaeth ffactorau amgylcheddol lleol megis maint ystafelloedd, y gallu i gadw pellter cymdeithasol a risgiau atal a rheoli haint wrth alluogi partneriaid i gadw cwmni i fenywod beichiog a mamau newydd yn ddiogel. Dylid defnyddio'r dull gweithredu hwn sydd wedi'i asesu yn ôl risg gyda gweithwyr iechyd proffesiynol perthnasol, timau atal a rheoli haint lleol ac Iechyd Cyhoeddus Cymru. Caiff pob menyw ei chefnogi i gael o leiaf un partner gyda hi pan fydd yn esgor, yr enedigaeth ei hun a'r cyfnod ar ôl yr enedigaeth, ac eithrio mewn nifer cyfyngedig iawn o amgylchiadau.
In addition to allowing for this flexibility the revised guidance has been amended for maternity services after listening to feedback from women and families and consulting with Heads of Midwifery and Sonography/Radiography Services. Visiting in maternity services will now be based on a risk assessment approach by health boards. This will take into consideration local environmental factors such as room sizes, ability to socially distance  and infection prevention and control risks in enabling partners to safely accompany pregnant women and new mothers. This risk assessed approach should be taken in collaboration with relevant health professionals, local infection prevention and control teams and Public Health Wales. All women will be supported to have at least one partner with them during active labour, birth and for the period immediately after the birth, except in an extremely limited number of circumstances.
