Wunzi2Grow – A Wunzi Infant System in Two Sizes
The Wunzi Infant System was inspired by the familiar “onesie” for infants. It provides a customizable body hug that improves trunk alignment and stabilizes the core, often leading to quick gains in trunk strength, body control, and mobility during the most critical months for infant development.
Now we’ve made it even better, by including the next size up so that you can keep up with a growing baby with one single purchase!
Key Benefits:
- It takes a minute or less to dress your infant – even the wiggle-worms – in a Wunzi.
- The diaper flap goes on over the diaper, and lowers easily for lightning-quick diaper changes.
- Closure tabs are embedded right into the garment – so no loose tabs to keep track of.
- The two Wunzi components are machine-washable, air-dry.
- The “next-size-up” configuration allows you to make one purchase, keep up with the baby’s growth, and keep those TheraTogs benefits going.

How to Purchase TheraTogs
Clinicians:
Login/Signup to the professionals-only side of the website for ordering options.
Caregivers:
Paying out-of-pocket? Consult with your therapist or rehab clinician to place an order with an authorized TheraTogs distributor.
Seeking reimbursement? Most payors require the order be processed via an O&P provider or DME (Durable Medical Equipment) facility. Find a Provider near you who is familiar with TheraTogs, or have your preferred Provider contact us for assistance in ordering.

Description
The acquisition of postural control – the foundation for functional use of the extremities – is paramount. When the innate drive to achieve and maintain verticality combines with deficits in core muscle balance, strength, and stability, the child will maintain an upright posture any way possible – usually by using her extremities for stabilizing, rather than for function.
– Beverly Cusick, PT MS NDT COF, TheraTogs inventor
By focusing on trunk stability and postural alignment, and giving the wearer thousands of repetitions in that improved alignment, the Wunzi delivers the massed practice that enables the therapist and caregiver to strengthen the core and improve upper body function – laying the foundation for even more advanced outcomes.
The new Wunzi2Grow configuration doubles the wear time – and extends the carryover benefits – of the Wunzi Infant System by providing two sizes in one purchase.

Guidelines for Wunzi System Measurements
For Torso Length measurement, measure down from C-7 (the big bone at the bottom of the neck) over the diaper and up to the child’s navel as shown below. Be careful to wrap the tape gently over the diaper. For Belly Girth, measure the infant’s belly circumference at the navel.
