What Sound does a Mommy make?

Heather was putting Jack to sleep one night not long ago, and he said the cutest thing. She was going through the animal noises, you know, what sound does a dog make, yadda, yadda, and she ran out of things that make sounds. So, spur of the moment, she asks Jack what sound a Mommy makes, and Jack though about it for a second, put his finger in the air and waved it and said, very slowly but deliberately, "No, no, no." Sooooooo cute, it kills me.
