This is an old thread, so it may be DC has had no more episodes and the issue has resolved?
If not - DD1 has seizures particularly around baths/showers. We think it’s the change of temperature, particularly on getting out, when it tends to feel cold.
Due to her sensory issues, she only has her bath lukewarm; but those aside, if the bath were quite hot, getting hot definitely causes her seizures!
If DC is still having episodes, if he has showers, I would suggest a shower chair. Bathrooms tend to have hard surfaces, which cause injuries if they fall, during a seizure.
DD1 likes baths, so we used to sit outside on the landing and talk to her. Now, she’s got used to being supervised; she accepts us, sitting in the bathroom with her.
DD1 started off with absences. I never saw one, as they happened at school. I sought a referral to the paediatrician. He got her to blow on a paper windmill and she had 4 absences. He referred her for an EEG. During the EEG, they flashed lights at her - iirc, only 5% of people have photosensitive epilepsy.
So, even if you can’t video one, I’d still ask to be referred, because consultants can get around that.
