The au was Underbeats. A musical au that Blue knew the girls loved. Every note, every key had Lumine smile from nonexistent ear to nonexistent ear everyday Blue was out on the streets with them. Cimmarian was always content to listen and was typically brought out to do so if she was upset or Blue was trying to get her to sleep. After leaving the Underground he'd gotten a job at a day care, a small apartment for him and the twins, among other necessities like food, a bed, a playpen for his girls, and toys to keep them occupied, highchairs, and a two seated stroller. This would be where they stayed for their first four years or so. Maybe longer. Blue didn't know yet. Now he watched with a loving smile as the girls worked on trying to crawl. Cimmarian was in a black skeleton onesie as she grabbed a teething ring and started to knaw on it. Lumine was in a white skeleton onsie as she wiggled and tried to lift herself into a crawl. Blue giggled at their cuteness. Blue grabbed a rattle and started to shake it temptingly. "Come to mama, you can do it!"

It didn't seem to take too long before they were zooming across the living room floor. Blue had baby gates prepared for this. Now was getting them to walk. They could start learning words and eating solid foods. "CAN YOU SAY, MAMA?" Blue asked as he tried to get both Lumine and Cimmarian to stand while bracing onto his legs. "Ba ba ba ple ba mmm." Was the response he got. "mmmmm ba!"
"Ok, LuLu, that was close. What about you, CiCi?" Cimmarian looked up at Blue with big yellow eyes. "Mmm, no." Despite his daughter's seeming defiance, Blue's eyelights exploded into stars. "OH MY STARS MY LITTLE CICI'S FIRST WORDS!!!!" He picked them up and nuzzled into them, cooing and enjoying the moment. "ma ma ma ma ma ma!" Lumine chirped repetitively, making Blue squeal. What were the chances that BOTH his babies would say their first words today?! He ALMOST wished Nightmare and Dream were here to hear them, but he tossed that thought out immediately. They were what got him to this point in the first place. He loved his girls dearly, but this wasn't supposed to happen. The girls sensed their mother's feelings immediately and pressed closer to Blue.

Blue cut up hotdogs for his girls and the other monster children in the daycare. The ABC's and other such learning songs droned on in the background to help with the little ones learning. After lunch, Blue would settle them all down for a routinely nap and read them a bedtime story. After the children would play and learn until he was relieved of his duties around five when the parents picked their babies up. It was a pretty easy job for Blue since he was already good with children and was a parent himself. Thus he also got paid pretty well. Blue put down the now cooled plates of hotdogs for the little ones to grab and eat. Blue watched carefully so they wouldn't over stuff themselves and choke. After, he rounded up his little troupe of nine (his girls included) and prepared them for a nap, having them go potty and grab their nighty time items. He got them down onto their sleep mats and switched the music to something more sleep related. Today's track seemed to be calming ocean sounds. Then he dimmed the lights and pulled out an all time favorite, Fluffy Bunny.
