My new girl, Lucy, loves the Bully chews & Himalayan chews that were recommended to me by other members here.  Maybe a nice hard chew would make your baby less likely to go after the molding.
 
Well, you well know the potty process is slow!  Are you using pads at all?  I'm not.  So far so good.  But I'm prepared for set backs also. 
Have you seen the vet yet?  On your visit, the vet will likely go over Reese very carefully - especially since you don't really know his complete history.   
Reese is a lovely little boy!  I'm new here also.  I've found that the members are all eager to help and offer support all the time.  It's a wonderful place to be. 
Enjoy your baby!

  Best wishes, Tracey
