This is kind of on you.

Whenever the kids go quiet - you know they are doing something they ain’t supposed to.

One time I thought our 5yo was asleep in her room for nap time.

So I decided to get frisky with my wife under the covers.

Wife starts making noise. And 5yo crawls out of the child dimension and goes, “Why are you making that noise?”

We had to pretend like she was having some pain and then she played doctor.
