Ex and I split up when DD was 5. She’s 14 now. Co parenting generally ok nowadays - nearly 50/50. But DD has been diagnosed with epilepsy after 2 seizures, both on school trips whilst very tired. So neither of us have yet seen a seizure. Saw private paed neuro, had mRI and EEG, he diagnosed epilepsy and advised go on medication. Ex is not keen - he has never been diagnosed but has had seizures in his life - only on waking, never another time. He thinks we can manage DD by not letting her get over/tired. That it has hardly affected his life so does not need to affect hers. I got a second appt through the NHS to get a second opinion. Again, diagnosed epilepsy and advised medication. He is still resistant. AIBU to push for DD to start medication despite his opposition - even if that means she spends more time with me? Because I know he is capable of sabotaging this, losing the medications etc …. My main concerns are SUDEP (she may stop breathing if has a seizure at night - highly unlikely but a risk) and that she is likely having mini seizures / lapses without us even knowing, affecting schooling, tiredness etc
