Ergonomics of Sitting: 90-90-90

Whether your child is seated at a table or a desk, it is important that they have a stable base of support from where to work. This is where the 90-90-90 rule comes from:

• Their feet should rest flat on the floor with a 90 degree angle at their ankles

• Their knees should be bent at a 90 degree angle and about 1-2 inches away from the seat of the chair

• Their hips should be at the back of their chair and positioned at a 90 degree angle

To create this 90-90-90 positioning, you may need to place something under your child's feet for them to touch a surface. Some suggestions for this include using a small footstool, using large books/old phone books, or a stiff memory foam pillow.

Create Spaces to Work, Play, and Relax

If you can, it is best to have a designated spot for your child to do homework, to play, and to relax. It is especially important for children with sensory processing differences to have a place that feels safe and decreases sensory stimulation. The pictures below were taken from an article by Alisha Grogan (2016). The article has many helpful hints (just ignore all of the ads that pop up - you do not need to purchase any items to create a quiet space for your child in your home). The main take-aways are to create a space in your home using items that are calming and relaxing for your child such as including favorite pillows, blankets, books, music and lights (maybe even a flashlight). I would also add, watch when your child goes to these quiet spaces so that you can build spending time here within their daily routine.
