First words?

I'm not 100% sure, still needs confirmation with a repeat occurrence, but I think on the way to bed last night, Joey said the correct word for bed! We always wave bye-bye to Daddy and the girls on the way back to his bedroom, and of course we repeat many times, "night night". I'm fairly certain during last night's bedtime ritual, he said it too, though it was more like, "nah nah", while he did his little circular wave:) Oh the excitement!!!
