There should be some recommendations, in general, for parents who come to know that their kids may have epilepsy. Of course, I am not nor ever will be a parent but I think I can see alot of it...even from the outside. So here are a few:
1) First, confirm that it is, actually, epilepsy before making judgement
2) Read, ask doctors and do everything possible to get knowledge on the exact kind and, if possible, reason for their childs version
3) DO NOT PANIC!!! ESPECIALLY IN FRONT OF YOUR KIDS!!! Your initial reaction, right in front of your kid, will do alot to determine how they will feel about their condition and themself for a long, long time.
4) To the greeeeaaatest possible extent, do not treat your child in any way different than you would treat them if they did not have epilepsy.
5) Be ready to answer questions, to the best of your ability, with the greatest honesty (as to how much should be determined by their age) without sounding overdramatic but with courtesy and being willing to answer more if they so desire.
6) Be happy and willing to research more on epilepsy while not dominating the attempt. Be a co-researcher, not a supervisor/supervised. The more your kid can find out, on their own, the more that the kid will be confident that they can handle the situation themselves.
7) If they so desire, take them to or help them get in touch with other epilepsy groups or organizations that they can talk to kids their own age. Communication with someone that has the same situation and that they can feel understands them goes a long way as well. (This is something that I never really had)
8 ) Encourage your kid in that epilepsy is not the end of everything. Even if something does not work right now, it is extremely likely that something will work soon.
I think many parents insert their own fear/denial/being lost into their child early on without thinking of the repurcussions later on.
Encouragement, anti-panic, interest without dominance and confidence will go a long way.
