Brief Report: Packing Treatment Comparison and Use of a Chaser to Increase Swallowing for a Clinical Case.
A quick sip of water after each bite erased packing and sped up swallowing for a preschooler with autism.
01Research in Context
What this study did
The team worked with one preschooler who had autism and packed every bite.
They compared four ways to end the mealtime stand-off: a sip of water, a spoon of smooth puree, brushing the food around the mouth, or just moving the spoon away.
Mom gave each tactic a turn in rapid rotation while the researchers timed how fast the child swallowed.
What they found
The tiny drink after each bite wiped packing out and pushed swallowing to 100%.
Swallowing happened faster with the drink than with brushing or moving on.
Puree worked, but the clear winner was the quick sip of water.
How this fits with other research
Griffith et al. (2012) showed the same thing a decade earlier: a chaser beats packing in three kids with feeding disorders.
Levin et al. (2014) bundled the chaser with other tricks and still saw success; Taylor (2022) proves the sip alone is enough, so you can skip the extra steps.
Whipple et al. (2020) used simultaneous presentation instead of a chaser and also cut packing, giving you two single-move options to pick from.
Why it matters
You now have a zero-cost, zero-escape tool for packing. Keep a cup of water at the table. After any bite that sits in the mouth, offer a tiny sip. No extra equipment, no tears, just swallow and move on. Try it first before layering in harder tactics.

03Original abstract
Packing involves not swallowing solids or liquids in the mouth. It is a significant mealtime behaviour to treat. Research has shown effectiveness of redistribution, but only two studies in highly specialised hospital settings in the United States have evaluated the use of a chaser. We extended this literature by conducting treatment in the home setting, and comparing a liquid and puree chaser separately to infant gum brush redistribution and a move-on to the next bite presentation component. A 4-year-old male with autism spectrum disorder and gastrostomy tube dependence participated in his home. We used a multielement single-case experimental design. With the liquid chaser, consumption increased to 100%. Swallowing latency was significantly lower with the liquid chaser compared to other packing treatments.
