Query: Always Performed As Expected

I use cloth / reusable wipes and I've never had a problem with the wipes drying out. I do rinse the pillow at least once a week (as the instructions state) and I have found that it could last longer than 3 months, but I change it every three months anyway to be on the safe side. To be sure I rinse it once a week, I simply rinse it every time I have to refill the warmer, which is about every 4-5 days anyway. The only time it ever even started to dry out was when I was lazy and didn't bother rinsing it for a couple weeks. Since then though, I've tried to perfect my wipes routine so we always have fresh warm wipes for my DD. :-)
