Chapter. 1

Phil Opened the door, "PHIL!" The Three Boys Stormed to the Front Door. "Who's Baby is that?" The Eldest one asked With a Bit of shock in their Voice "I Don't know but I found them in The Ruined Temple." Phil Answers as he Walked to the living room setting the Baby down onto the Sofa, " Techno, Go get a Bucket of Warm Water and a Towel for me. Wilbur Get Some Clean Clothes And Tommy... Get me A Plushie." They ran off to get the Stuff. Tommy came back with a Teddy bear, Techno with the Bucket and Towel, And Wilbur With the clean clothes "Oi! Isn't that my Shirt?!" Tommy Yelled, Wilbur Snarled " Well CHILD! It doesn't fit you anymore So might as well give it to the Baby." Wilbur Spat " Boys Please, You will wake up the-" Phil Tried to say before the Baby Opened its eyes and Cried "Oh Jeez." Phil Picked them up and cradled them to Stop Crying, " This Reminds Me Off Tommy Back then." Phil said as he Chuckled Looking down at the Toddler, The Boys Stood Quiet before Sitting down on the carpet.  "So That's Our New Sibling?" Tommy Asked with Glittering eyes, Wilbur Giggeld at Tommy's Excitement "Well, Y'know Phil's Addiction with adopting Kids." Techno Said with a Smirk Looking at Phil "Okay That's Now just RUDE. But Maybe one more edition in the Family is Alright." Phil spoke Softly as he looked down at the Baby "What will we name them?" Wilbur Asked Curiously, "We will do that Tomorrow But first Let me clean them." Phil Said as He took the Towel and dipped it in the warm Water, He Gently Wiped the Baby's Face After the cleaning Phil Changed the Baby into the Clean clothes that Wilbur Bought. "If we Have a New edition in the Family, Doesn't that mean we need space for the Baby?" Wilbur asked, "What Will Our friends say if we have a New Baby Sibling?" Tommy asked, "We get more clout Yooo-" Techno said with a mischief smile. "Okay, Guys Its late let's go rest now!" Phil Said with a Smile, " Aw, No Phil! Come on, I'm not tired." Tommy Whined "Tommy, you're a Big Brother now so act like one!" Wilbur said smacking him behind the head. The Three went up the stairs Bickering at each other, Making Phil Smile as he Followed them up "Goodnight Boys, Have sweet Dreams!" Phil Said Before Closing his door "Goodnight Phil!" They Said in sync.

A/n:Well, As my Old Followers Know, I deleted the Old Story to Begin a Long Series where Y/n is there when they're just a Baby till they're an Adult (I think if I have the Motivation to do so). This Story May have 10-20 Chapters, so Buckel up for this Crazy Story.
