| Structural Criteria | The Lull Kids Standard | Typical Unverified Imports |
|---|---|---|
| Therapeutic Core Engineering | Developed with pediatric occupational therapists and independently lab-tested to ASTM F963-23 and CPSIA standards. Formulated with precise jaw-grading feedback bounds to prevent jaw muscle overuse. | Typically mass-produced without documented clinical input. |
| Material Density & Rigidity | High-Density Solid Core Silicone Chew Bricks are molded at a firm 70A and Teething Straws at a softer 60A; custom durometers are available on bulk and OEM orders for heavier chewers. | Often hollow-molded, without published durability testing for sustained chewing. |
| Toxicology Certification | Accredited Third-Party Lab Verified ASTM F963-23 & CPSIA tested — lead, phthalates, and heavy elements all pass. Reports available for download. | Typically self-certified, without accessible third-party lab reports. |
| Surface Architecture | Dual-Tactile Therapy Faces Combines high-resistance studs and calming micro-dots. | Often single-texture, with limited sensory feedback. |

Need a firmer or softer bite for a specific student? Custom durometers — including 80A for aggressive chewers — are available on bulk & OEM orders, so you can match the tool to the individual.
How clinicians use it
Three ways OTs, SLPs, and special-education teams put calibrated oral input to work — and which tool fits each.
Proprioceptive input & regulation
Deep-pressure input to the jaw is organizing for many sensory-seeking students. A firm 70A Chew Brick gives sustained resistance for self-regulation before seeking escalates to clothing, collars, or pencils.
Jaw-grading with calibrated firmness
Match resistance to bite force: a softer 60A Teething Straw for lighter oral input, a 70A Brick for stronger chewers, and custom durometers on bulk orders for the heaviest. Dual-texture faces let you grade feedback within one tool.
Classroom focus support
A discreet, neutral tool redirects oral seeking into a socially appropriate outlet, so an ADHD or anxious student can stay at their desk and on task. Write access into the student’s plan so it isn’t withdrawn as a behavior consequence.
What Caregivers & Clinicians Say
“I introduced the chewies to my kindergarten students in the ASD classroom setting that I work in as an SEA. It's a great tool to use when the students need something to help regulate their wiggly bodies. Oftentimes during group lessons, they have a lot of energy and need to move around. Once they find something to help calm their bodies, they are still vocal and may suck on their hand or chew their shirt. Your chewy is a great tool for them to chew on. In a matter of moments, they calm down and have the opportunity to focus on what is being presented. I appreciate that they are firm and can handle the rigors of our chewy friends.”
Andrew H.
Special Education Assistant
Waite Park Elementary
“I was especially impressed with how well made and durable the tools are. They feel sturdy enough to hold up to regular use, while still being comfortable and appealing for students who benefit from that sensory input.”
Emily Fait
Life Skills / Autistic Support Teacher, Franklin Regional School District
“My 8-year-old was constantly chewing his shirt collars to shreds at school. Since introducing the Lull Kids chew bricks, he regulates beautifully. Absolute lifesaver for school anxiety.”
Nicole H.
Parent of child with ADHD
“I have found them helpful, and I will recommend them to my client's parents. I found that the children with ADHD and also autism liked them.”
Christa S.
Licensed Clinical Professional Counselor
Center for Children
“The tools were for my nephew, who has autism and oral-motor and sensory processing deficits, and he absolutely loves them!”
Sheneequa B.
Certified Occupational Therapy Assistant
“As a pediatric OT, finding durable chew tools that reach the posterior molars without triggering a gag reflex is incredibly difficult. Lull Kids Bricks are my gold standard. The dual texture provides perfect sensory feedback.”
Sarah Jenkins, OTR/L
Pediatric Occupational Therapist
“Our special education department bought these in bulk for multiple classrooms. They are indestructible compared to standard hollow chew products, and being completely dishwasher-safe makes classroom sanitation effortless.”
Marcus Vance
Special Education Director

About Lull Kids
Lull Kids is a family-founded company from Houston, Texas. We started with a simple frustration: the sensory chew tools available to families and therapists were either too soft to survive real chewing or made with materials nobody could verify.
So we built our own — Developed with pediatric occupational therapists and independently lab-tested to ASTM F963-23 and CPSIA standards. Molded from dense food-grade silicone, and independently lab tested before anything ships. Today, our chew tools are trusted in 20,000+ homes, classrooms, and therapy clinics across the country, helping kids, teens, and adults regulate wherever they need it.
Families buy direct right here. Clinics, schools, and hospitals order direct too — with volume pricing, purchase orders, and Net-30 terms — and we answer our own phone.
Frequently Asked Questions
Everything families ask before buying direct.
How does the bundle discount work?
Buy two 4-packs and the 20% discount applies automatically at checkout.
What if the chew tools are not right for my child?
Every order is covered by our no-questions-asked money-back guarantee. If they are not right for your family, just contact us and we will make it right.
How do I clean them?
Sensory Chew Bricks and Teething Straws are dishwasher-safe, and they can also be washed with warm soapy water.
Are they safe?
Yes. The chew tools are made from 100% safe silicone. Developed with pediatric occupational therapists and independently lab-tested to ASTM F963-23 and CPSIA standards.
Should I choose the Chew Brick or the Teething Straw?
Choose the Sensory Chew Brick for a solid-core, dual-texture chew tool for stronger chewers. Choose the Teething Straw for lighter oral input and younger chewers — a softer 60A hollow-core straw, available on Amazon.
What age are the Sensory Chew Bricks designed for?
Ages 5 and up (kids, teens, and adults with autism, ADHD, and sensory processing differences). Adult supervision is recommended, especially for aggressive chewers. For younger children (6 months to 3 years), see our Teething Straws.
How long does a Sensory Chew Brick last?
Chew tools are consumables: lifespan depends on chewing intensity. Inspect regularly and replace worn units rather than pushing them past their lifespan. They are dishwasher-safe for classroom sanitation routines.
What are sensory chew tools?
Sensory chew tools are clinical-grade silicone devices students chew to meet oral sensory needs — a safe, purpose-built alternative to chewing shirt collars, pencils, and sleeves.
