I barely ever disinfect toys unless a child wipes their nose on a stuffy or sneezes directly on something.
If it is a matter of mouthing things then I am not too worried. Most of the kids are over 2 and barely put stuff in their mouth and I only have one infant who does still taste everything.

personally I find the smell of bleach and possible risks much worse and same with Lysol. I did find that superstore has a natural disinfectant spray so once I wipe down teh change table i use the disinfectant spray that is natural on it.

I have a very small group of kids and barely ever any turn over so I am not too worried about the germs on toys.

Like some others have said - I am much more worried about the kids not covering their mouth and coughing directly on each other or close to each other's face or sneezing and wiping noses on things around the house.

We are really vigilant about hand washing here - even for the kids

I also mop and clean the house a lot

The toys occassionally go through a sanitation cycle in the dishwasher if they ended up in the bathroom on the floor or in some dire circumstance but I really don't worry about the toys much
