Finding peace in a frantic world by Mark Williams & Danny Penman. This has an 8 week course that you can do using a CD and the book. I have completed it and cannot recommend it highly enough.
Sitting still like a frog by Eline Snel (mindfulness for kids). I have tried this when teaching in schools and on my own children. They really love it, finding it very calming and relaxing. It starts to give children an awareness of their bodies and the changes that can happen depending how they feel. They learn to use the breath as a means of grounding themselves.
These are apps that people have recommended to me. I have personally used Headspace and Calm. I suggest taking a look at a few to decide what will suit your needs best. Most of them offer free trials.
- Headspace – this seems the most popular amongst people that I know.
- The mindfulness app
