My answer is based on personal experience with my son.
1. I hope that the first time the convulsions that have come to his son, drove him to the hospital to make the necessary checks.
2. Revealed that it is only of seizures, should have prescribed tranquilizers, administered rectally (as is the quickest way to assimilation).
3. The convulsions in the first years of life are common in many children, will tend to disappear on their own without specific treatment (apart from calming to be administered only if there are actually seizures), already at 6 / 7 years there should be no more problems.
Try to calm down the agitation does not correct the problem that if controlled at the time of the attack, does not create serious problems.
If you feel the need for peace of mind, ask your doctor with her or in the hospital, where he surely will also give information brochures on the subject.
I'll give you my best wishes, I know what he's trying, and I'm close. A big kiss to her puppy
