Chin prompt plus re-presentation as treatment for expulsion in children with feeding disorders.

Four kids with feeding disorders kept spitting out food during meals. Re-presentation alone did not stop the spitting.

The team added a gentle chin prompt right after each re-presented bite. They tracked how often food came back out.

Expulsion dropped to almost zero for every child once the chin prompt was added. The change was immediate and stayed low.

The simple two-step move—re-present, then prompt—worked when re-present alone had failed.

Shalev et al. (2018) later copied the idea with drinks. They also saw near-zero liquid expulsion when the chin prompt was added.

Rubio et al. (2021) pooled many physical-guidance studies. Their review calls finger prompts and side deposit the most reliable, but the chin prompt still fits under their "physical guidance" umbrella.

Firth et al. (2001) and Dougherty et al. (1996) showed earlier that any physical guidance beats non-removal of spoon for food refusal. The 2011 paper narrows the focus to expulsion and gives a quick, low-force option.

If a child spits out most bites, try re-presenting the food once. If the food still flies, add a light chin prompt—two fingers under the jaw, gentle upward pressure. You should see the spitting stop within the first few trials. No extra equipment, no long parent training, just one clean prompt after the re-present.
