This was a lucky raffle commission pic by  wen. A tender moment like this is great. See original image at http://www.furaffinity.net/view/28612655/ . I've also written a story to go with it:

Nanny Wen was busy babysitting Miriam Silktail. Wen had looked after many adult babies in her time, but this 59 year old mouse was the oldest she had ever had. Miriam’s daughter Suetina had entrusted the bunnysitter to take good care of her elderly baby until she got back from work to pick her up.

After keeping Miriam content on the sofa with some baby toys and Tots Television Channel cartoons on the TV, Miriam was growing noticeably sleepy and her stomach audibly grumbled for food. “Come her Miriam Sweetie” Wen cooed “Time to take your milk”.

Miriam rolled over on all fours on the big sofa and crawled nearer to her bunnysitter, her diaper crinkling as she moved. When she was close to Wen’s knees, the carer gently rolled Miriam on her back, sat down and rested the old mouse’s head on her lap. For an elderly furry in diapers, a pacifier hanging round her neck and pink booties, she looked very cute, young and innocent.

Wen reached over the sofa for the dressing table and got an adult baby bottle of milk with bunny designs around it. The insulation in the bottle had kept the frothy milk all lukewarm and fresh. “Ma Milk?” Miriam babbled. “Yes dearie, it’s baby’s milk” Wen said softly “Open wide”.

Wen directed the bottle towards Miriam’s mouth and the elder baby complied and let it slip between her teeth, then began to suckle. She was rewarded with a sweet and fruity flavour in the milk.

Wen held on to Miriam’s head for comfort, all the while stroking the soft fur and keeping the bottle steady, while Baby Miriam sucked and drank her milk. While she was drinking, the mouse looked at Wen with awe and fondness as she would a mother. It had been over thirty years since Miriam had a mother and now she was happy to be looked after one once more.

Wen returned a smile and look of fondness back at her baby. This was a tender moment for both of them. If Miriam had a bottomless stomach and Wen had a bottle that never ran out, they would have a neverending moment like this to enjoy.

By now Miriam had halfway finished her bottle but continued to suck contentedly. “That’s it drink up mousie. Drink till baby’s fed and full” Wen told her. Miriam mumbled quietly and carefully flexed her legs, arms and head as she drank up. Both baby and babysitter felt like they were both in baby heaven.

As Miriam nearly finished her milk, she failed to notice the full feeling in her lower regions. Without any warning her diaper grew warm, wet and yellow at the front. Wen’s ears and nose twitched and she turned to look and noticed that Miriam’s diaper was soaked all around the front.

“Oh! Looks like baby made a wetsy” Wen said pretending to be surprised. Miriam didn’t seem to hear her fully as she finished the last drops of milk from her bottle. Wen took the empty bottle, put it aside, then got up and lay Miriam’s head down on a cushion.

“Does baby need a burpie?” Wen asked. Miriam didn’t answer and suddenly realised how wet her diaper was. “Mee diapie’s wet!” she moaned. “Don’t worry sweetie, I’ll change you soon” coaxed her babysitter.

Wen ran her paws across Miriam’s belly and chest up and down several times, triggering deep breaths and wriggling from the big baby. The stimulation got to her stomach and soon, the baby mouse made quite a loud number of burps.

“Okay baby’s tummy’s better” Wen said “Now let’s get your diaper changed”. Miriam lay back and sighed blissfully as her carer got a box of wipes then began to undo the tapes. Using the dry parts of the diaper, Wen wiped her diaper area clean then applied a wipe for a good measure.

“Does baby need another diaper?” Wen asked as she reached into a package of ABU Fuchsia diapers placed on the floor “Yes she does. Yes she does”. She pulled out a fresh diaper from the open package and slid it under Miriam’s bottom. Carefully Wen assembled the sides of the diaper and secured the two tapes together.

“There. Baby’s all clean and fluffy” Wen said and she gave the front of the diaper a few soft pats. Miriam smiled at the bunnysitter and a yawn escaped from her mouth. “Mmmhmm. Baby’s getting sleepy” Wen remarked “Time for Lil’ Miriam to have her naptime”.

With those words, Wen slipped the pacifier round Miriam's neck into her mouth. The sleepy mouse suckled and lay back on the sofa. The kind and caring Wen brought a soft blankie and a plush toy and the sweet old baby cuddled them in her arms. Finally Wen gave Miriam a kiss on her forehead and Miriam fell into a restful sleep. Wen left to attend to her own housework. An hour later, she would spend more quality time with Suetina’s lovable baby.
