Future Conversations About Sneaking Out

When they are older, I'm sure they will be more subtle with the secret conversations...but until then, this is what Drew and I woke up to this morning.

Rosa:  laba laba laba...shoes.
Emmy:  (in a whispered voice) Rosa.
Rosa:  poopee?  What doin?
Emmy:  Rooooosa.
Rosa:  numa numa numa shoe...poopee..shay shay shay shay.
Emmy:  Rosa Rosa Rosa Rosa Rosa Rosa Rosa Rosa.
Rosa:  sheeeeeeeeepiiiingggggg (sleeping).
Emmy:  Roooooooooooooooossssssssssssaaaaaaaa.
Rosa:  poopee!

I'm wondering which words are code.
