'We're quite good at thinking outside the box: Early autistic sensory experiences expressed by autistic adults and caregivers of autistic children.

Sensory differences are well documented in autistic individuals. However, early sensory experiences have not been fully explored, particularly from the perspective of autistic people. We sought to understand early sensory experiences in autism from the perspective of autistic adults (some of whom also had autistic children) and caregivers of autistic children (some of whom also had a personal autism diagnosis). Using a qualitative descriptive design, aligned with a constructivist paradigm, focus groups were conducted with 3 autistic adults and 12 caregivers of autistic children. Data were analysed with reflexive thematic analysis. Five themes were generated accounting for early sensory experiences in autism: (1) Acknowledging the uniqueness of sensory preferences, (2) Negative impacts of different sensory experiences, (3) Feeling different and the pursuit of belonging, (4) Controlling sensory experiences to support daily function, and finally (5) Overcoming the challenges of the sensory world. The findings highlight the specific sensory needs of autistic children in early childhood and the adaptability of caregivers. This information can help young autistic people and caregivers advocate the importance of recognising the uniqueness of each autistic child's sensory preferences when seeking support.Lay AbstractSensory behaviours in early childhood can impact how autistic children experience and engage in the world. There is a lot of research about sensory differences in autistic children; however, there is very little known about experiences in early childhood. We asked 3 autistic adults and 12 caregivers of autistic children about their/their child's experiences of sensory behaviours in early childhood. In our sample, autistic adults and caregivers of autistic children shared similar experiences about the challenges they/their children face related to sensory experiences in early childhood and how they overcame these. The findings can influence how researchers and service providers view sensory preferences in early childhood by understanding that everyone's preferences are unique, and the importance of advocating for what works for each autistic person.
