SIDS...

Re
I just read something online about how SIDS peaks at 2 months and my son is a month and a half. I also read that it happens more in premature babies and boys. Now I'm going to be constantly stressing about it... I wasn't worried about it before but now I am.. my son was born 5 weeks earlier then he was supposed to be..  I really hope SIDS doesn't happen.. anyone else extremely worried about it?...
