Most forms of epilepsy don't have a well defined inheritance, so by that, the chances of your child inheriting it are small. For some specific forms, the inheritance is well defined and tests can be done to determine the probability of inheritance. You need to find out whether the type of epilepsy your husband suffers from is highly inheritable or not, or subsequent to physical trauma. Ask your doctor and if he/she doesn't know, ask for referal to a specialist who may know.
