Hi, it is a very common problem, esp with newborn, hatchling stage pleo Rb. They usually grow out of it. It scared the Holy Furry Kitties out of me
when it happened to my very first Pleo rb in 2010, BABY, and I have seen it several times in my other Pleo RB when also at this same stage.
The important thing to remember is to turn the baby off if it keeps clicking or if they won't turn off to pull the battery, I did not know this the first time it happened with myne, and it went on way too long. You do learn the longer you have baby Rb and after talking to other members finding out it is normal or not and what to do, That is what I love about this forum. Good luck and I am sure your pleo will grow out of it. RWM
