Translation?

Last night when we took Declan to his room for bed he said something to me I picked him up as usual and while holding him he looked directly at me and said "Mommy ....you're ??????"

I have no idea what he said I am.

Daddy thinks he said "you're boss" which makes sense but In hoping it was "you're best". He was smiling when he said it.

He then turned to Daddy and said "Daddy you're _______." Which I think may have been "you're badass".
