  I agree.  To the OP...my opinion is that you are expecting a bit too much out of your tiny one....perfect potty training, no messes, running.  Go slow with him, he's still an infant..... 
Oh!  he's at the informative time and the fear fact age; introduce nothing that is out of the ordinary during his 8, 12, 16 and 24 weeks...
