Hi Boey. It sounds like your little people think there is something blocking their path to where they need to go with the sock or wrapper. Since they cannot take the sock/wrapper where it needs to go, they choose to do something else instead. You can read more about it in this post.

To help your little people with this problem see #2 in "D. Tips for managing your little family's home" located in the Helpful VF2 iOS Tips & Answers post. Good luck!
