I'm giving Mommy a hard time

Recently at a friend's house, Elisabeth perched on their couch in a "Moses' basket" (a woven bassinet for an infant). Elisabeth, in her excitement, nearly dumped the basket and its contents (herself) onto the floor. My wife jumped to her aid and kept her from falling. She said, "You almost gave Mommy a heart attack!" Elisabeth grinned and said,

"I'm giving Mommy a hard time."

Close enough.
