How do i disinfect toys?

[Willow]

The hard plastic kind can be put in the top drawer of the dishwasher, this works really well

Good luck, doesn't sound like much fun

Soft toys without batteries etc, can be hot washed with disinfectant and you can wipe over any that do have batteries with a little diluted disinfectant (soft or hard ones). I would do anything that can be submersed just like you described (fill up a laundry bag and do them all in the laundry sink at once) Lay everything out in the sun to dry as that is a great bacteria killer.
It's ok to mention it to the staff at the kindy too, and ask what they do to disinfect and help stop the spread of disease. They should get the hint if you don't want to ask them outright to make sure it's done, IYKWIM? Google the information on how it spreads so that you can show them specifics.
