15-16 months to ~3 years
5.5 ins (14 cm) long x 8.0 ins (20.0 cm) in wrap around girth x 1.5 mm thick
The child should have about 7.5 ins (20.5 cm) of length from the beginning of the underarm to the wrist. To ensure a secure fit and performance, we recommend 0.5 ins (1.25 cm) as the minimum amount of overlap on the wrap-around portion.
The S-Early Intervention size is very effective on a wide-range of children with both higher and lower muscle tone. It is a sound selection if your child is growing out of toddlerhood and is of average size for their age. As noted previously, we recommend avoiding bracing the entire length of the arm if possible (underarm to wrist). Consider the M-Younger Grade School size for children greater than 3.5 years and in cases of spasticity (ie. cerebral palsy) or in children who have a very strong, determined urge to interact with the head, neck and face in an unwanted behaviour.
