As a speech pathologist, I also work with children on their feeding and swallowing skills. One of the most common questions I get following an evaluation is, "What is rotary chewing?"
Rotary chewing refers to chewing food on both sides of the mouth, as well as using the tongue to move food from side to side. The jaw will form a circular movement pattern when using proper rotary chewing.
In typical development, children should be using rotary chewing by 18-30 months of age.
Many children who are referred for feeding and/or myofunctional therapy are using a munching chewing pattern, which is incorrect. Munching chewing refers to chewing on either one or both sides without moving food side to side with the tongue.
Why is proper chewing important? Proper chewing develops tongue and face muscles. It also allows children to eat a wider variety of foods and textures. In addition, there is a relationship between correct chewing and speech sound production.
How can families practice at home? Gum is a great way to practice at home! Allow your child to have a half piece of gum, and practice chewing several times on each side and moving the gum from side to side with the tongue. A mirror is also helpful.
Readers: Do you have picky eaters at home? Have you tried using gum to help with proper chewing?
