The Challenging Behaviour Foundation (CBF) have set up a new Covid-19 page on their website which they will keep updated with relevant information and resources. The page will be updated regularly as new information is produced.

In many instances, isolation is likely to lead to behaviour changes so their first priority has been to produce an information sheet "Challenging behaviour - supporting your loved one at home" along with a more visual summary of the same information "Supporting children and adults with severe learing disabilities at home during the coronavirus pandemic" 

They have also put all their challenging behaviour DVDs online so anyone can access them free here: https://www.challengingbehaviour.org.uk/information/covid19information.html
