Your child finds writing physically difficult and tiring due to motor coordination
Pencil grip, sloped board (or a lever arch file works!), timer
Dyspraxia makes the physical act of writing exhausting because the brain has to work much harder to coordinate fine motor movements. Ergonomic tools reduce the physical strain, shorter writing sessions prevent fatigue-induced frustration, and alternatives like typing bypass the motor difficulty entirely.
Relevant from age 5 onwards when formal writing begins. The earlier you introduce supports, the less negative association builds up around writing.
A parent bought a sloped writing board (actually just a lever arch file) and a chunky pencil grip for under £5 total. Their child went from refusing to write to completing short tasks without tears. The wrist angle change made that much difference.
