Sterilizing equipment

Or

Im 37 weeks and Im just wondering when I should start to sterilize my breast pumps, bottles and dummies?

Im aware the baby could take up to 5 weeks to arrive (if I go overdue), so me and my SO are wondering if its ok to do it before, or if it makes more sense to wait until she is born?

Sorry if this seems like a silly question but I cant find answers anywhere!
