I downloaded this app after a recommendation to help my son with his sleep, his ADHD means at times at bedtime he struggles to switch his brain off & get to sleep. This app has verbal breathing, relaxation, body scan and sound mindfulness exercises which are useful to anyone struggling with sleep, very child friendly but also to adults, I will definitely be giving it a go!
