We studied the experience of professional support among first-time mothers in relation to a scale measuring professional support in maternity care. We used a qualitative study with both an inductive and deductive approach and interviewed nine mothers. Our findings, both inductive and deductive, suggest that first-time mothers expect professional support in their transition into motherhood, building a bridge between two worlds. The first meeting, acknowledging individual needs, and supporting partner participation were important for good support. Maternity care should be organized with a focus on availability and professional support for mothers and the increased participation of their partners. Our scale of measurement can be useful but needs some development.
