I usually brush Bee's teeth before going to sleep.
Getting her mouth open is very difficult.
"OK, open your mouth wide!"
I encouraged her by telling her,
"Good! I would be so thankful if you usually open your mouth like this."
My encouragement might have been too much.
She pulled her lips up apart, forming a brutal-looking face.
It was so funny!
