Question for those who have baby boys!

Hi ladies, As I've been told I am expecting a boy and having a girl, I have no knowledge on this, just wondered if some of you could shed light onto the topic of circumcision? My OH is circumcised and I know quite a lot of men who are and not for religious reasons but for preventing health probs. I've been advised by a lot of male friends that it is better to circumcise as it is more hygienic and just wondered what your views are, if you have or have not circumcised your baby boys and if you have, when is the best time to do this??? Thanks everyone, Eva x
