Don't let the fact that you have seizures stop you from experiencing childbirth! I've had seizures for 25 years, during this time I have given birth 3 times -- 2 daughters and 1 son. I won't say it will be without worry. According to the medications you need to take to control seizure episodes during pregnacy, there can be certain risk to the unborn child. This is the norm if taking any medicaion during pregnancy.
I was taken phenobarbitol when I gave birth to my first 2 daughters and I had only been on felbatol 1 year when I got pregnant with my son. My last pregnancy was extremely hard (especially not knowing what might happen to my unborn child). At that time, felbatol had not been tested for it's effects during pregnancy. I became the "human ginnie pig" or at least this is the way I felt. The weight of what could be was always on my mind. But, what I can say is, there is a god! Today I have a wonderful boy, who is 10 years old. His only problem is that he is 2-years delayed (in every area) -- but he lights up any room he walks into!!
Yes, I was stressed while pregnant; but, it was worth it all!
