How do i explain epilepsy to my girlfriends 6 year old son

Caring question!: You sound so nice! thank you on behalf of everyone. Each 6 yr old is different, but - use simple descriptive words & small installments. "something happens to me at times. Don't worry. I'll tell you about it". In a few days, add a bit & ask if he remembers the last time. Ask for ?'s. Kids may have seen a seizure, so you may not start at zero.
