How often should I switch my baby's pacifier?

I would change every 3 months too. Or even earlier if i sees the pacifier is cloudy. If you can, buy like 4 pacifier at a time & baby will use different ones, if that is so won't worn out just one. Can even last longer. Haha! To me my baby's pacifier is like a fashion accessory for him. So have different colours for different outfits.
