Child Mesh not connected to parent mesh after anim montage plays.

I am using the elephant with tusks from the market place African pack to randomly roam around a flat gray landscape. I play an anim montage of the elephant eating. Afterwards the tusks are no longer connected to their socket on the elephants head and float in front of the elephant. The tusks are a child of the elephant mesh. I can only select the elephant mesh (without the tusk mesh) to connect to the ‘self’ input on the anim montage.

So my question is: do i need to check a box somewhere to make the child not separate and to make the tusks stay connected while roaming?? Not sure what to look for.

Any help would be appreciated. Thank you.
