Can anyone do this toddler rig perfectly?

Hi thyagom not sure if i'm understand your question correctly... (or anyone else without more info).

Your link dates to a post from before the release of toddlers, to a rig that's made based on the game-files found in the fullbuilds at that time. If you need a functional toddler rig to create poses; open the latest version of S4S select Animation --> Clip Pack or Override and export the Toddler rig from there.
