And mom does not take well to advice, so venting on here helps a little, since there is not much I can do about it. Mom is one of those first time moms who calls herself a "momma bear" and knows everything about kids. I guess my 17 years of childcare experience makes me an amateur compared to her! 
I would probably look to replace. The fact is you have no control over what she's feeding him (or allowing him to get in to
) but you have to deal with the fall out.
She clearly is clueless and I imagine it will only get worse. I see this conversation in your future "I know he's only 18 months, but he refused to leave the house unless I gave him a can of Mountain Dew to drink! Isn't he so funny/clever/smart? Just in case he seems a little wild today!"
