Hi, I've been lurking for about 6 months now.
His behavior is a symptom. SPD children cannot control it. They "act out", "explode", "misbehave" because they are seeking something, futiley searching for how they can meet a need they feel within themself that they cannot articulate.
And that is where OT comes in. The daycare is just going to have to get on board - give them info of what he needs to "focus" and "center" himself. He cannot do it on his own.
His behavior will improve as his SPD is treated. It's hard but really, you might consider telling them NOT to discipline traditionally - as he's not willfully misbehaving. I promise you - he's not.
Check out the SPD checklist at this website - www.sensory-processing-disorder.com so you can figure out exactly what areas and in what way (over-responsive, under-responsive) and then you can work up a sensory diet (also available on that site is information on sensory diets)
Share the sensory diet with the daycare or ANY provider actually, family members, the school, etc.
Education and awareness are the keys.
Hi! I'm also new to the boards-
My son is almost 3 (he will be 10/12).
