Transitional foods are foods which start as one texture and change into another texture when moisture like water or saliva is added or when a change in temperature changes.
For example, Wotsits, chocolate buttons, Pom Bears. Minimal chewing should be required for these but they are good to teach and practise chewing skills.
Be aware of foods such as ice cream and jelly which change from a solid to a liquid as they melt so should not be given to child with modified fluid texture recommendations.
