Baby ear protection?

So.. Since we live out in the country, we run some pretty loud stuff. Tractors, skid steers, 4-wheelers, down to the riding lawn mowers. Have any of you used ear protection for your little ones? What are your thoughts? One of us will baby wear Charlie while we're running things, but only if we can find the right kind of protection.

    We have thought about the safety of it on the ride on mower but my husband doesn't even wear anything. He's hard of hearing anyways but that's no excuse. It might change if we ever get a big tractor though. I think we should have two pairs of whatever for hubby and a child size for when the children ride with him or I.
