Anyone's DC had a febrile convulsion at under 6 months of age?

According to the doctor's they don't happen until after 6 months of age but my friend thinks her DS had one yesterday.

My dd2 was 16 months. It was very obvious what it was - she lost conciousness, eyes rolled to the back of her head, saliva bubbling out of her mouth, and arms and legs jerking rhythmically. I phoned an ambulance. She diodn't fully regain conciousness for 30 minutes or so.

It might well happen, most gp's haven't heard of febrile convulsions in children over 5 but both my mum and sister had them at 10 and my DS had 2 today at 13.
