Age regression is your coping mechanism, yet you were awkward to even admit that it was your coping but Dean had figured out after noticing little signs, at first he teased you about it but when you explained why you did it and that it was a coping mechanism, and after Dean did some research, he became your caregiver and god he adored you, he also loved making you feel little after a long day, he'd do things such as: Tie your shoelaces for you, asking if you want to color in or he'd tell you that your to little to do something or he'd call you "Little one".
Well, after a big hunt you had regressed and also gone nonverbal. You was looking for Dean as you held your dinosaur stuffie with a proud smile.
Dean had heard your footsteps and glanced up from his dad's journal and grinned seeing you holding your stuffie and your paci already in. "Hey, bud." He greeted as he put the journal down as he got up and walked over to you and gently ruffled your hair.
"Someone feelin' little, yeah?" He cooed at you.
Dean smiled softly as he watched you nod, lord did he adore you. You're his baby.
