A/N: I'm very excited to write this one, thank you for the request! I hope you enjoy it! Also, this is extra-long because I had way too much fun writing it. It's 3031 words. Usually, my one-shots are around 1000 to 1500 words so that just shows how much I loved doing it lol

" Come on, Suki, it's time to go to momma Inko's house!" Izuku called from downstairs. Katsuki was entrusted with getting himself dressed that morning. Was it a good idea for Izuku to give him the responsibility? For big Suki maybe, but for little Suki? Not so much.

" Comin, dada!" The caregiver could hear his thumping footsteps from the above floor as the little rushed to grab his things. He was fairly proud of the outfit he'd chosen and he was excited to show his dada what a big boy he could be.

Just as Izuku was about to yell for him again, he saw the blonde rush downstairs so fast he nearly slipped and tumbled down them. " Hey now, be careful, angel." He said, just now getting a look at Katsuki's choice of fashion.

The boy was wearing one of Izuku's oversized t-shirts -- oversized on him at least -- paired with a pair of space-themed leggings and a pink tutu over top. He wore his favorite pair of custom Deku and Ground Zero converse with some shin-length white socks to complete the look.

Izuku couldn't help but chuckle at the sight. It was absolutely adorable how proud his Suki was of his outfit. Unfortunately, though, he knew his mother didn't know about Katsuki's age regression. Which meant that he had to somehow convince his little firecracker to change clothes. He was most definitely going to have to tell his mother they would be late.

" No, dada, I wanna wear dis one! Not dat one, dat one stupid!" Katsuki crossed his arms over his chest and stomped his foot on the ground to get his point across. Not that it was needed, Izuku knew full well that he didn't want to wear the outfit he picked out for his little.

" That wasn't very nice, Suki. Dada is only trying to help you. It's too hot out for you to wear that and you know momma Inko doesn't know about you being my little Suki bear. You're gonna have to work with me here, kid. How about you can still wear my shirt but you let me pick the rest, hm?" It was a reasonable compromise. One the caregiver had had to make several times prior.

Katsuki thought it over for a moment. It didn't take long for him to cave, but that did not mean that he was happy about it. " Dada mean." He said to himself as Izuku slipped a pair of shorts on him.

" I know you're upset, baby, but Dada just wants to make sure you're comfortable. Maybe next time we go to momma Inko's I'll let you wear whatever you want. We can even tell her about little Suki if you'd like to. Does that sound good?" Izuku finished up tying the knot on the little's shoes and stood up. He made sure to put together an outfit that matched the aforementioned converse too, Katsuki doesn't go a day without wearing them. They were a gift for their second wedding anniversary and he'd worn them every day since.

Katsuki lit up at the question, nodding profusely at him. He'd wanted to tell Inko about his age regression for many years but never did for fear of rejection. Inko was such a good mother figure to him and he never wanted to lose that. But Izuku was confident that his mother would accept him for who he was.

The two arrived at Izuku's mother's house, Katsuki being fully out of headspace by then. As soon as they stepped through the front door, they were both nearly tackled to the ground in a hug. " Oh, my boys! I've missed you so much!" She cried out, squeezing just a tad bit too tight.
