I have discovered this excellent app "Thinkninja" that is used by lots of outside agencies to help children develop their emotional health and wellbeing. It is aimed at 10 -18 year olds and helps with the regulations of emotions, empowering  children to develop resilience, manage emotional health and fulfill their potential. The app helps with regulation of feelings in an age appropriate way. It is currently free on app stores to allow for children to explore their feelings about the currrent global situation. It is worth looking at and seeing if it is useful for your child. The app has been developed with psychologists guidance and the fact it is used by agencies who  work within the emotional health field suggests its validity for supporting our children through this crisis and beyond, as our children are developing and changing all the time and sometimes struggle to manage their emotional health.
