Surgery on a 3-year-old

Hello, Our 3-year-old daughter has had seizures since she was 9 mo old. She was diagnosed with infantile spasms. She is significantly developmentally delayed, on numerous medication and still has between 0 and 6 seizures a night (almost exclusively in sleep). We just found out that she is a surgical candidate and we are hoping that she will have her operation soon at Boston Children's (Dr. Madsen). My greatest concern is for the "invasive monitoring" which sounds awful not to mention our inability to explain any of this to our poor, unsuspecting little girl. It seems that her seizures are originating from the right temporal/frontal regions. Does anyone hae any words of wisdom on this topic? TIA jessicarozen@yahoo.com
