"bundle" of joy

Logan has recently picked up a really obnoxious habit...

...he likes to stick his hand into his mouth...right after he's been given a bite of food.

And then he promptly smears it all over 
e-v-e-r-y-t-h-i-n-g.

So...

I put him in a make-shift straight-jacket.

(a big kitchen towel I can tie behind his neck like a bib, but tuck behind his back and leave his arms pinned)

 

Help me.
