A new mother who was detained in a psychiatric hospital for five weeks says she "felt like a prisoner" because she was separated from her baby.
Shelley Browne, who had postpartum psychosis, was admitted under a mental health order after giving birth three years ago.
In Great Britain mothers are cared for in specialist mother and baby units, but women in Northern Ireland are admitted to general psychiatric wards, separated from their babies.
The business case for a mother and baby unit is months overdue, but the Department of Health (DoH) said it was well developed.
