"bathing soup"

Sophie came out of the bathroom last night in her usual after-bath attire…her diaper.
She ran back to the bathroom and, a few minutes later, came back to the kitchen where I was and she had on my bikini top.

“Look mama! Your bathing soup!”

Then she grabbed her crotch and said, “Where’s the trinket box…? Let’s go find it!”

Turns out a “trinket box” is actually a bathing soup bottom.
Kids really do say the darndest things.
