Breastmilk

It was when her baby girl confesses her did Alya notice the pressure that had been building in her breasts. It never ceased to amaze her how punctual littles could be with their schedules, Marinette always knowing when snack-time was.

Alya undid the buttons of her shirt as Marinette crawled onto the couch next to her. Alya unclipped the left half of her nursing bra as she reclined back onto the couch, Marinette too big to nurse on Alya's lap, as Marinette latched onto the nipple and started taking milk in. Alya undid the other half of the bra, her nipple dark and leaking a little.

"Adrien, don't you want some milk? It's good for you."

Adrien hesitated, blushing, though less out of awkwardness than embarrassment as his tummy made a loud rubbling whine. He was clearly very hungry. Alya held back a laugh.

"Come here baby boy. Let's fill that tummy up."

The blonde little took that as all the permission her needed and crawled onto the other side of the couch and started nursing, Alya softly petting each of her baby's hair as she fed them.

A person's biological needs tended to differ between classifications. For littles, their biological clocks moved slower than their peers; they retained their baby-fat for a longer period, they didn't grow body hair until they reach their twenties, their nutritional needs are different, not to mention their troubles with potty-training when in their headspace.

Caregivers like Alya had their own set of biological differences. Most notably, the hormones of a female caregiver tend to cause certain parts of their biology to progress faster than their peers. Most notably, it's common for caregivers like Alya to experience galactorrhea, or lactation without pregnancy. Biologists think that caregivers develop like this to act as surrogates for other women in the tribe in case of **** or other problems, though that's merely speculation. Caregiver milk in particular is considered highly nutritious and will often provide the nutritional needs of littles as old as 30.

Alya started producing milk less than a week since she received her classification and she had been breastfeeding Marinette shortly after she became her chief caregiver. Often times, when Marinette wasn't around or not in the right headspace, she would pump and store bottles of it, either leaving them for Marinette at her house or bottle-feeding Marinette when out in public.

It also came with the added benefit of having larger than average breasts, something her boyfriend Nino certainly appreciated.

When she started looking after Adrien, she took to breastfeeding him too. Being an affection-starved boy with a missing mommy and emotionally-distant daddy, Alya figured that he got more emotional satisfaction from it than physical.
