If you have a child who struggles to communicate to anyone at school when they are overwhlemed and they just withdraw (which goes unnoticed!), do you have any advice/tips/ideas of how to work around this? Our OT suggested we find a way for ds to let the teacher know if he needs a time out, he won't verbalise it and is a bit too old for the emotions card type keyrings. Looking for other ideas that aren't too 'young' and are subtle so his classmates don't notice. Thank you :)
