My daughter loves sitting in the shed watching me. generally I only use hand tools when she is there but occasionally need to use the saw. Although when I do this she wears my earmuffs they are way to big so my parents bought her a set of peltor kids muffs for her first birthday. I think it is a great idea and it installs PPE as being a normal thing. I use to be terrible with PPE before I worked in the mining industry and as someone who worked in the safety department I know how hard it is to change people after years of bad practice.

I bought them off ebay and would highly recommend the buyer, they even came with a suitably decorated hand made tote bag, a great little selling point. Here is the link to the seller - I have no affiliation.
