I always try to watch the match with my youngest boy, we have always won when he has sat with me. However he is only 18 months old and trying to get him to keep still is a difficulty. I have found gaffer tape to work particularly well over the last few matches.
I always have to shave on match day otherwise we lose, and often we lose anyway, so it's a bit of a **** superstition come to think of it. Meh
