I humbly suggest that what I have put together may be a partial answer for your query. I am on a mission to provide at least a million children with this practical, supportive and capability-enhancing material. It's a handbook just released on Amazon, particularly for times like we're in, but initially started to help situations more like you describe. Compassion in Action: Emotional First-Aid for Children. If you will send me your direct email via mine, I will happily donate an eBook copy to you for use in your mission - Jondi
