I'm very naughty too, and I eat the macca's sundaes too. I have had maybe 4-5 sundaes and maybe 4 shakes this pregnancy. And I agree Fletch (although I understand where you are coming from Sarah) that I dont trust the little guy in can on the street either.
Mind you - I had a dozen freshly opened raw oysters last week, so I'm hardly the pin up girl for being safe.
