you're my best

Braxton say's to me, "I love you mom, you're my best."
"Your best?" I ask, "what does that mean?"
"It means your my best mom."
"Thank you Braxton," I say...."that makes mommy feel really happy. You are my best Braxton."
It's turned into a phrase around here. If Jeff makes me really happy then I tell him, "you're my best." I have always thought the phrase was cliche' but when my little boy said it to me it made my whole world.
