Parents of children with hearing loss (HL) often navigate an unfamiliar and uncertain path. This qualitative study investigated the nature of parental uncertainty: (1) immediately after a child's HL was identified; (2) prior to primary school entry; and (3) during primary school. Open-ended questions in online surveys were completed by participants (N = 61) with: (a) personal experience as a parent of a child with HL (n = 35); (b) professional experience with children who have HL (n = 19); or (c) a combination of both parental and professional experience (n = 7). Six major themes were abstracted using thematic analysis, including uncertainty about: (1) the Pervasive Impact of HL, (2) the Nature and Causes of HL, (3) Developmental Impacts, (4) Family Life, (5) Family Decision-Making, and (6) Education and Support Services. The salience of these depended on the stage in time following identification.
