I am seeing a 3 y.o. girl with PDD who is wonderfully high functioning and has very involved parents. She has some sensory issues and particularly HATES having her hair brushed. During our session, even though she was hyped up on sugar following speech therapy, after some deep pressure through shoulders and head (GENTLY, GENTLY, GENTLY! HAVE AN OT SHOW YOU FIRST!) she sat there and let me brush and do her hair. Then we took it out and had mom repeat the process w/o difficulty, and mom was really happy to have learned something she could directly apply at home. If kid and parent leave feeling happy and more knowledgable, then I feel like I did my job well that day.
