I don't know where Tanner has come up with it lately, but he's taken to calling daddy "Lola". And, he knows it's funny. He'll come up and start talking to "Looo-la" and then start giggling so much that he can't continue.
Morgan has quite a few lately.
"Mommy, there's a flea!"
"Honey, that's not a flea, it's a fly"
"No, mommy, that's a flea."
"Morgan, let me wipe your nose it's running."
"My nose is not running, it just has snot coming out of it."
And, of course, if we laugh at her, we get this:
"Mommy, don't laugh to me!"
