Hi! You might find some helpful information with your 8 yr old's situation in my Profile, About Me: I was able to post alot of information in regards to that issue... feel welcomed to check it out if you'd like to. I even have some websites listed which help provide products that contain the germs but leave a child still 'feeling' what they've done, to continue motivating them to try to get better and resolve their issue! We use these with my autistic five yr old now, they help alot! :)
