"I will tell him that his Auntie Nan said he has to learn how to say her name right! LOL"
Good! And if he cries, tell him he'd better stop because his Auntie Nan says there's a great, big Boogie Monster who listens veeeeeery sharply for the sound of little children crying. And, when the Boogie Monster hears crying, he follows the sound until he finds the crying children. And, once he finds them, HE EATS THEM UP!
I've got lotsa great child-rearing advice! I oughta write a book! :)
