This came in a quick burst of inspiration.

Lily watched in amusement as her husband suddenly became busy cleaning the counter—with a sponge no less.

"Scurgify," she said, lazily sweeping her wand and watching as the counters cleaned themselves.

"No, it's okay Lily, I can clean by hand," insisted James, not looking at her as he continued to scrub.

"Since when have you taken up using muggle means of cleaning?" she demanded, raising an eyebrow.

James swallowed as he turned to give her a lopsided grin. "Professor McGonagall always said it builds character."

Lily shook her head. "You have enough character as it is."

James's eyes shifted desperately around the kitchen. "C'mon Lily," he pleaded. "Just this once can you do it for me? Please?"

"Your 'just this once' happened two days ago when you suddenly remembered you had something to do at work. And you had another 'just this once' when you took an interest in gardening last week. And another 'just this once' when your hands somehow got tied up in the shower curtain yesterday."

"I swear Padfoot put a jinx on it the last time he was here," James cried.

"Must have been a James-only jinx because it certainly didn't entangle me," smirked Lily.

Her husband ran a hand through his hair, for all his height, looking like a first year cornered by a teacher. His lips turned down and he gave her the most ridiculous puppy eyes he'd ever used. She almost took pity on him. Almost, but not quite. "Please Lily," he begged.

"All this time you've spent trying to avoid it, you could've gotten it over with."

"Please," he tried again. She wondered if he was going to fall to his knees in the next second and beg at her feet.

She rolled her eyes. "James, you got yourself into this. I told you it wasn't going to be all fun and games."

"And I said I believed you!"

Lily's shoulders shook as she laughed. "And I'm glad you did. Now, come on. It'll be over before you know it."

James dragged his feet as he crossed the kitchen as if she had sentenced him to detention during quidditch practice. He cast her one last pleading look as he passed her on his way out.

She shook her head firmly. "Not this time."

His shoulders slumped as he trudged through the living room and up the stairs, followed closely by Lily. She followed him down the hallway until they came to a door.

"Please, Lils," he said quietly.

"Uh-uh."

He leaned his head against the door and took a breath. He'd accused her of being a drama queen but no one could put on a show like James Potter when it came time to changing his son's nappy.

Lily reached around him and opened the door.

Harry lay in his cot, burbling as he played with a miniature quaffle James had insisted they get him.

At the sound of their entrance he looked up and let out an excited cry.

"Hey mate," sighed James.

Harry laughed and abandoned his quaffle as he reached toward his father and made a grabbing motion with his tiny hand.

James strode to Harry's cot and lifted him out. He lifted Harry above his head, holding the baby just beyond the reach of his glasses. "Mummy's making me change your diaper, so co-operate little guy."

Harry laughed and James seemed to take this as agreement. He put Harry on the changing table. Lily moved in behind him and handed him a clean nappy.

James unzipped Harry's blue and white striped pajama and made a horrible gagging noise. "Bloody hell!" he managed.

"James!"

Her husband jerked around to glare at her. "Did you put a dung bomb in his diaper as a joke?"

"No," replied Lily tersely, trying to hold her breath against the smell coming from Harry's nappy. The baby stared up at his parents, his green eyes, so like Lily's, shifting between them.

"I am not opening that!"

Lily honestly couldn't blame him. "Just get it over with," she ordered.

He snatched the clean nappy from her and tucked it beneath his arm. They both took a deep breath and stopped breathing as James undid Harry's nappy.

Lily waved her wand the moment she could, and they expelled a loud sigh of relief. Harry laughed and waved his arms.

James cleaned Harry and put on the new nappy.

"What did you feed him?" James demanded when Harry's pajamas were on once again.

"Nothing out of the ordinary. I—," suddenly she recalled wondering what had happened to the blueberries she had bought for a pie.

"James, you didn't give Harry any of my blueberries while I was out, did you?" she asked doubtfully.

James grinned sheepishly. "We may've had a few. Harry seemed to like them."

"I told you not to give him any blueberries! That's why it smelled so bad!"

"Blueberries did that to him! Blo—," Lily glared at him and he hastily amended, "blimey! Hey, it's not like he understands me!" He picked up Harry. "I won't ever do that to myself again, mate. I promise you that."

Harry burbled and ran his fingers over his pajamas. With his downcast eyes and frown of concentration, it almost seemed as if he were apologetic.

Lily patted James's arm. "You did well," she told him.

James grinned at her and shifted Harry to his left arm so he could drape the other over Lily's shoulders. "I thought so too," he said brightly, without a trace of his earlier reluctance. "You know, I think I deserve a kiss for that."

She rolled her eyes at him.

Yes, it's true, blueberries do that to babies. I know from personal experience.
