“Prop” is the short-term for proprioception, which is deep muscle/joint body input.
If your child loves bear hugs and squeezes it may be because it helps his body feel calm. Deep pressure does that to our nervous systems and helps us feel comfortable in our bodies so that we move comfortably through life.
With the new school year upon us provide more opportunities for your child’s body to regulate and feel calm. One easy way to do this is to allow her to open public doors. They tend to be weighted and require deep muscle activation, thereby activating the parasympathetic nervous system (the part that is responsible for relaxation). If the door is too heavy for your child give a little support but still allow her to do some of the work. Doing this throughout the day will proactively regulate her brain chemicals so she feels pleasant inside and acts pleasant outside.
So let them “prop” the door open as you slowly walk through and give them a smile.
