Boohanti Bedtime

Every night, in order to get her to turn over on her back so I can
put on her diaper (yes, it's time she no longer wore one at night),
Sevi says I must recite the code. It's always boohanti three times
and another secret word. I guess words at random and then she says
"give up?" and tells me. Tonight it was boohanti boohanti boohanti
caterpillar, but then she added another, "worm" Once I'd said it all
she dutifully rolled over and I put on the diaper.
