These do work, and they are helpful for my child. It keeps him from putting straws too far in his mouth, I do think it would be cool of these were made out of silicone vs hard plastic.
Straw mouthpieces to help improve oral motor skills|||ARK's Lip Blok® mouthpieces are simple yet effective oral motor tools. They naturally exercise the mouth muscles to discourage tongue-thrusting, promote tongue retraction, and correct overall tongue positioning. They also prevent individuals from biting the straw or putting it too far into their mouths. Simply press them into the top of a straw, and drink.
Lip Bloks come in three different mouthpiece lengths – 3⁄4” (yellow), 1⁄2” (blue), and 1⁄4” (teal). For the best results, start with the longest 3⁄4” length. Once the individual becomes accustomed to that length, switch to the 1⁄2”, and then finally to the 1⁄4”. This hierarchy slowly teaches individuals to put less and less of the straw into their mouths. When only 1⁄4” is inside the mouth, fluid is deposited in the front of the mouth where it is easier to manage and less likely to cause coughing or aspiration. With shorter lengths, you also get a better oral motor workout, as the tongue retracts more, the lips seal better, and the cheeks have more tension. Lip Bloks fit into most standard drinking straws (measuring approximately .25" in diameter). Cups and straws sold separately, or you can add compatible straws via the pull-down menu above.
Lip Bloks are sold in singles (1 packs) or in a combo of 1 of each size. Select which option you'd like from the pull-down menu above. Colors may vary.
