Hi Leah,
Her immune system may be weaker from medications or from things you've had to do to prevent the seizures. I don't think the seizures are what cause a weakened immune system. I had febrile seizures. So did my oldest daughter. I was a sickly kid but my mother did every medication the doctor told her I needed. When I was old enough to think things through on my own I started building my immune system. Absorbable vitamins, supplements, chiropractic care and good nutrition and exercise. My daughter hasnt had the same problems I had because I tried to strengthen her immune system to prevent the sickness to prevent the seizures...she had few seizures over 24 months.
If you'd like more specifics about building her immune system I'll be glad to share. I believe our bodies are wonderfully resilient and can withstand a lot.
God bless,
M.
