4. Rivalry

"Ow!"

There was shuffling, followed by groaning as Marshall fumbled for the lamp by the bed. "You okay, honey?"

Mumbling angrily, Mary shifted and flung her arm over her eyes as she tried to alleviate the pressure in her womb. "The rugrats are playing tag on my bladder."

"Oh…" He sounded relieved as he scooted down and rested his head lightly on her abdomen.

One of the babies delivered a kick that nailed Marshall in the head, and Mary let out an unladylike snort.

"Looks like someone's jealous."

Marshall rubbed the side of his head and patted her belly affectionately.

"I thought the term was sibling rivalry."
