I needed to check this up with Grammar Girl again! ūüėČ And¬†I wasn’t really surprised to read that the spelling of do’s and don’ts is inconsistent. Even style guides and usage books don’t appear to agree on the correct punctuation.

The¬†Chicago Manual of Style¬†and others recommend¬†dos and don’ts.¬†The Associated Press and others recommend¬†do’s and don’ts. While¬†Eats, Shoots & Leaves¬†(on my bookshelf) recommends¬†do’s and don’t’s.

Whichever version you choose, just be consistent!
