# Food-grade LSR Baby Number Blocks Teething Toy
---
Made 100% from food-grade liquid silicone rubber, our number blocks teething toy is formulated to be non-toxic, odorless, and free of BPA, phthalates, PVC, and other harmful additives that are commonly restricted in infant products. Each block features raised number shapes and textured surfaces that provide gentle stimulation to sore, swollen gums, helping to reduce teething discomfort and encourage natural chewing development. Unlike traditional wooden or hard plastic teething toys, our LSR construction delivers a soft, flexible bite that won’t damage emerging baby teeth or irritate sensitive gum tissue.
This product is manufactured as a single-piece LSR molding, eliminating gaps, seams, or small detachable parts that could pose a choking hazard. The compact block design is sized specifically for small infant hands to grip, helping to build fine motor skills and hand-eye coordination while introducing basic number recognition from an early age.

Our number blocks are manufactured via precision liquid injection molding, with the following controlled process parameters:

Unlike many generic teething toys that use lower-grade silicone or plastic additives, our product is produced exclusively with food-grade LSR sourced from qualified raw material suppliers. The single-piece seamless molding eliminates hidden crevices where bacteria can grow, and the inert silicone structure does not support microbial growth, keeping your baby safe during daily use. All raw material batches are tested for harmful substance content before production, ensuring full compliance with global infant product safety standards.
The 35 Shore A hardness is specifically calibrated for infant teething: it is soft enough to provide gentle relief for swollen gums, yet firm enough to withstand repeated biting and chewing without tearing or deforming. LSR material retains its flexibility and performance over years of use, even with repeated boiling or dishwashing sterilization, so the toy can be reused for multiple children or passed down as an educational toy. Unlike wooden toys, it will not crack, splinter, or absorb moisture, and unlike plastic toys, it will not become brittle or leach chemicals when exposed to high temperatures during sterilization.
Each block is shaped to fit comfortably in small infant hands, encouraging independent grasping that builds fine motor skills and hand-eye coordination. The raised 3D number shapes on each face provide additional texture for chewing and help babies become familiar with number forms through tactile exploration. The soft, muted color options are designed to be gentle on developing infant eyesight while supporting early color recognition.
The non-porous surface of LSR does not absorb food, saliva, or odors, making it extremely easy to clean. Our teething blocks are compatible with all common sterilization methods, including boiling sterilization (up to 10 minutes of continuous boiling), steam sterilization, dishwasher top-rack cleaning, and chemical sterilization with infant-friendly disinfectant solutions, without degrading the material or releasing harmful substances.

We offer the standard 35 Shore A hardness as the default option, which is ideal for most infants in the active teething stage. For customers looking for alternative firmness:
Please specify your required hardness when placing a custom order.
Our standard product uses 40 × 40 × 40 mm individual blocks, which is optimized for 3–12 month old infants to grip. We can accommodate custom size requests for bulk orders: common alternative sizes are 35mm for smaller hands and 50mm for use as larger toddler building blocks.
All of our baby teething toys are produced with food-grade LSR as standard, which meets all global safety requirements for infant products. We do not offer lower-grade material options for this product line, as safety is our top priority for infant use. If you require specific compliance testing for your regional market (such as CPSC testing for the US market), we can arrange third-party testing per your request.
