Hi Persephone,
Thanks for your suggestion.
She's really pretty good in comparison to what she could be getting up to. And it's not that she's unsupervised, sometimes the temptation is just too good sitting there in front of her nose (and usually noticed pretty quickly by me)! She definitely has enough toys. I'm just really after something as a preventative measure. That's a good point that some things will not be good for surfaces - will definitely keep that in mind.
