These suggestions by Angie Voss, OTR, are essential for every family with children who have sensory processing difficulties.

Sensory retreats allow children’s nervous systems to calm and reorganize.  They should be incorporated into the child’s routine several times a day.  I suggest scheduling sensory retreats before challenging activities, such as mealtimes, homework or bedtime.

Angie also highlights the importance of having a retreat from overwhelming sensory stimuli while out in the community. Follow the link for practical strategies.
