Do you let your kids play on the floor even at times you haven't disinfected it yet?

To be honest, I am guilty of doing this. I often let my kid play on the floor when it is not disinfected. I used to be very fussy earlier but as she is growing older I get tired of policing her all the time. So, I let her be at times. But at times I think that too much adherence to all this also makes a child immunity week. We have grown up playing in mud and sand, and we are doing fine.
