So, I bought my 2 kids wieghted blankets (they are ASD).
They help a lot.
I didn't buy the most expensive ones & they don't have a removeable cover.
A mistake ... my teen Ds has been sleeping directly under his, with no PJ's.
So, a hot soapy wash pre winter, then into an old single duvet cover is wise.
However, I' m a bit worried the weight of it might break my washing machine?
