I think a lot of people were mentioning OT because the term in the title, "sensory seeking", is a term associated with sensory integration dysfunction/sensory processing disorder. OT's can do assessments that identify the sensory issues that are adversely influencing a child's ability to function.

We got an OT assessment because my son was having trouble in preschool. Without getting into it all, if you looked at the results of his OT assessment compared to his preschool environment, we were basically sending him to his own sensory hell everyday. It was no wonder he was miserable there. We pulled him out, started OT and he started K as an early entrant six months later. He still sees his OT and he is doing great in K.
