3-year old girl epilepsy

Dear All, My 3-year old daughter is bright, intelligent, full of energy, always want to have her companionship to concentrate on her, but also has quite abrupt temper changes from being happy and jolly to nervous, stubborn and angry (I believe it is common among girls/women). Something like half a year ago, we have noticed that during having fun on the trampoline, she abruptly stopped jumping and needed to have a sit for 3-5 seconds with her face muscles stretched. From that day, we see that she is experiencing that more/less on the daily basis, having 3 to 10 of such episodes. It lasts up to 10 seconds, it seems that she is fully conscious during that episode, because she is answering the questions while being asked at that moment (but she is not doing it with dexterity and quickness as usual). It seems that she is also having feelings that the episode is coming because she is leaving her activity and having a sit before that. She has developed her own description for that phase saying “I need to think for a while”, but as indicated by her she is not experiencing any pain during that moment. What is quite often, it happens that she pees/has problems with keeping her pee during that moment. As said, she is 3 years old and still wears diaper during the night and sometimes during the day (sometimes she indicates that the wants to pee/sometimes she forgets). We have diagnosed her in our hospital. Magnetic resonance and CAT scan were ok, EEG was bad showing the discharges. She started to take Depakene (valproic acid) with minimal dose at the beginning of July and up-to-date we do not see any improvement in her well-being. Currently, the doctors want to increase the dose, but we have second thought and would like to better understand what we are fighting with and that we are not hurting/intoxicating her without reason. I am writing to you to ask, if:there is anyone that happened to experience similar signs and how he is handling them. Any comment, would be highly appreciated. Thank you.
