Do weighted blankets, ear defenders and sensory toys work?

The short answer

A sensory product is useful only when it helps a child do a named activity more comfortably or safely. Weighted blankets have limited and mixed evidence. They require individual risk assessment, active consent and supervision; the child must be able to remove the blanket, and it must never be used for restraint or left on overnight. Ear defenders may protect access during a defined noisy event, but routine all-day use can increase sound sensitivity and block speech or safety information. Fidgets, chewable items and movement equipment need an equally clear purpose, suitable materials and a way to review their effect. Trial one tool in one situation. Record participation, distress, safety and recovery, then keep, change or stop it according to the result.

• Start with the activity that is inaccessible, not a shopping list of sensory products.
• Evidence for weighted blankets is limited and mixed, and safe use requires more than choosing a weight.
• Ear defenders can help in defined loud settings but should not become automatic all-day wear.
• Fidgets and other tools need a purpose, safe use and an observable review.
• A child can withdraw consent even when a product previously seemed helpful.
