New Word!

Jo has a new word!
She has already been saying mamama, and da and she says somethings close to Doug for both boys. She says num num for yummy foods and she waves bye-bye, shakes her head for no (and when you say no no she shakes her head).
Well, yesterday twice...at different times of day, she smiled at the cat and when I said cat she said "..at"
It is her first real word!
