Hi! My soon to be 3 year old son has had febrile seizures since the age of 1. Like you son they increased in quantity. After like the 4th time he got sick, was seen by a neurologist and placed on seizure medication. It got to the point where he was having like 3 in a row ... when his temp reached like 103.7 was when he would get them. Last time he got sick, he only had one, thank God. At the first sign of fever, I have to take him to the dr. and start him on tylenol and motrin. I have suppositories and even neproxin (sp.) to keep his temp down. He has had to be admitted to the hospital like 3 times because of his seizures. The doctors keep telling me that they grow out of it by age 5 ... but 5 is still a long 2 years away for me. The key for my son is to keep his temperature down. Other than that, he is a healthy, smart almost 3 year old! Good luck, but take your son to a doctor to get refferred to a neurologist.
