This is what we do a couple of times a day. This is obviously 1st thing in the morning if my hair is any indication.
We spin Cortland on his back counter-clockwise to help with his speech. And the side spin is done with C facing into the spin and we can go either direction as long as he's going forward. This affects his vestibular system and helps with balance and coordination.
He actually asks to be spun now which leads me to believe that along with the obvious improvements we've seen, the spinning also makes him feel better.
Alan's dad made the board with 1/2 plywood cut to 38"x 24". He purchased a wooden lazy susan from Big Lots and then replaced the spinning part with one purchased from Home Depot that is rated up to 500 lbs. I then cut the corners off and covered with upholstery fabric over several layers of quilt liner.
I've never seen my actual expressions when trying to understand what Cortland is trying to say. Just so you know, I must make those faces a whole freaking lot since lately he's always trying to say something.
