Osamu - little 

Age range - 6m to 1yo

  -In the miyas household-( they are on the couch and the parents died years ago and no this is NOT an incest)(sorry if i made them to OOC)

   Nobody P.O.V "Oi 'Samu" Atsumu called."Yeah 'Tsumu?""C'mere." Atsumu held his arms open for Osamu to lay down."Ok?" (We stan non-toxic twins) Atsumu P.O.V- I wrapped my arms around 'Samu as he layed down on my chest.I rubbed circles on his back as I stroked his hair with my other hand.

  "Ya' know ya' can tell me anything, right?" I asked him. "Yeah?" "I just wanna know one thing." I pulled a fox binkie out of my pocket.As soon as I took it out, 'Samu shot up with wide eyes."'m not mad or anythin' but, why do ya' have this?" "I-uh-" 'Samu burst into tears before he could finish his sentence.(NOOOOO- POOR BABYY LET ME HOLD YOU PLSSS- 😭🤚)

  "Hey- "I sat up and tried to calm him down "-Its ok 'm not mad 'Samu." I pulled him into a hug and gentley bounced him on my knee. (we Stan non-toxic twins and please atsumu is such a good brother and osamu is just straight up cute) "It's ok-shhhh-it's ok 'Samu you're okay." I gentley wiped his tears away with my thumb. "Are ya' a little 'Samu?" I asked him softly.He just nodded his head."Aww bubs, why didn't cha' tell me, I would've helped ya know?"I said with a smile on my face. "Ya' don't think 'm a freak or weird?" He asked softly."I would never think that, bubs." (AAACCKKKKKK-TOO ADORABLE- GONNA DIE_)

  "Thank ya' 'Tsumu." I gave him a smile in return. "Ya' feeling small right now?" He nods his head in repsonse. "Do ya' have any little gear 'Samu?" "It's in our room." "Let's go get it then." I followed Samu up the stairs to our bedroom. He pulled out a box from under the bed, with little gear inside it."Alright let's get ya' changed bubs." I took out a pack of diapers, a fox onsie, a bottle, and I got out the binkie from my pocket.

  "Hey 'Samu, what is yer' age range for when ya' regress by the way?" "Um-well a uh- 6-6ix month old to 1 year old" 'Samu replied with pink dusted onto his face. Osamu P.O.V- "Awww I have such a small baby brother!" 'Tsumu pinched my cheek as he said this "S-Shaddap." Atsumu P.O.V- "Ok ok ill stop, lets just get ya changed." I placed 'Samu gently on the bed while put the diaper on him and the onsie, which he looked cute in. (EEKKK- smol samu 🥺)

  "Yer' so cute baby boy im gonna die cause of yer cuteness" I said to a now fully regressed 'Samu who, only giggled in response. I plopped the binkie in his mouth to which he happily sucked on."Aww what the heck." I snapped a couple of photo's of 'Samu before I placed him on my hip and went downstairs to make him his bottle.(Im just gonna say what we are all thinking : I would take photo's too)  I sat 'Samu down on the kitchen counter as I poured the milk in the bottle and added some sugar and vanilla for flavor. While I put 'Samu's bottle in the microwave , I turn around to see him making grabby hands at me. "C'mere bubsie." I gentley pick him up and sway him back and forth. "'Chumu, baba weady yet?" 'Samu said this in the most adorable voice ever. ( OK BUT HIM NOT BEING ABLE TO SAY TSUMU SO HE SAYS CHUMU IS JUST----EEEKKKKK)

  "Speak o' the d3vil, yer' bottles already done 'Samu." I grabbed the bottle and poured little drops on my forearm just to make sure it wasn't to hot for 'Samu. I carry 'Samu up to our bedroom and sit down with him cradled in my arms. I take the binkie out of his mouth and 'Samu lets out a small whine.

   "Sorry bubs but I cant feed ya' if ya' have your binkie in yer' mouth." I chuckle at the last part. "Here ya' go bubs," I feed 'Samu as I rock him gently in my arms. Osamu P.O.V- Icky thoughts start to come to me and tears start to well up in my eyes as the icky thoughts make their way into my brain." Woah bubs what's wrong?" 'Tsumu takes the bottle away and places me on his knee." I-I hab icky thwoughts ans-" I couldn't even finish my sentence so I just bury my head in 'Tsumu's shoulder. (NOOOOO- DONT LISTEN TO THE ICKY THOUGHTS WE ALL LOVE YOU SAMUUUU)))

  "Aww bubs, listen to me. Don't listen to those icky thoughts okay, whatever they say is not true okay?" I just give a small nod. 'Tsumu starts bouncing me on his knee, rubbing my back with one hand, and stroking my hair with the other. Soon enough I calm down. "Tank 'ou bubba."  (Im crying rn- this is too much cuteness)

  "Anytime bubs." 'Tsumu give me a kiss on my cheek and another one on my forehead."Can I's hab mwy baba now 'Chumu?" " Of course you can baby boy!" 'Tsumu says this with a warm smile. He cradles me with one hand while using the other to feed me. I feel myself getting sleepier and sleepier as he rocks me gentley back and forth. Atsumu P.O.V- I lay down on the bed with 'Samu on my chest. I plop his binkie in his mouth before giving him a small kiss on the forehead."G'night 'Samu." I give him another small kiss on the head before I fall asleep with 'Samu in my arms. (Im just imagining this scene and- *dies of cuteness*) A/N This is my first time writing anything like this so im sorry if its not good.
