When a young child is upset, we frequently give them oral motor input like a pacifier or a bottle.  Oral input is calming.  As kids get older though, it is more concerning to see them putting items in their mouths.

Sometimes children do not process information from their oral sensory system efficiently, and therefore engage in oral sensory behaviors. They may need additional oral motor input. Telling children to not mouth items will be ineffective, as they may have a sensory need they are trying to meet.

Many children with unique sensory needs mouth and chew objects for oral motor input.
