12 weeks - Manage as low risk and high risk
In high risk MDT - Individualize the frequency of visits and at each visit ensure involving other specialities
- avoid triggers
- ensure AED compliance
- asses seizure frequency
-consider AED level - Serial growth scan from 28 weeks

increase seizures potential
