One-to-one midwifery care means different things to different people.
Some take it to mean one-to-one care throughout the whole pregnancy, labour and postnatal period. This is obviously ideal but not practical in all settings or possible; there is usually a back-up midwife who can take over care where the named midwife is not available for any kind of reasons.
Some parents-to-be come into the hospital in labour under the illusion that they will only have one midwife, not understanding the shift patterns or that midwives need breaks. Some think this is not proper one-to-one labour care as parents have to meet and form new relationships with strangers but I would like to argue that it can actually be of benefit to get a new midwife into the mix; either to reiterate what has been advised already or to come in with new energy or ideas to help the woman in her labour.
Some midwives can just walk into a room and say a few poignant phrases and pieces of advice that where there was whaling and disillusion within a few contractions there is calm and ‘yes! I can do this’ spirit. This is maybe a little of an extreme example but I do find that often there is a benefit to have a fresh midwife take over labour care at the end of a long shift, especially if midwife has not had a proper break.
Where one-on-one care really makes a difference is where the women have supportive partners and birth partners who understands that labour is not an illness but more of a quest that the woman has to go thru. Those partners give encouragement, they make the environment nice with music and lighting, take them for walks, gives them cuddles and kisses, they rub their back /feet /cramps /hands /scalp /shoulders, ensure they hydrate, take snacks and shield them from the world making them feel safe. If this is in place, it doesn’t really matter who the midwife is.
