so um, youre not active very often but i hope this gets to you, im having trouble finding a supercorp fic where kara doesnt tell lena she regresses, but lena finds out after a couple months of kara hiding her little stuff (paci, colouring books etc.) and lena fimds her box of stuff one day when kara is at work and she tells lena to look in her closet for something to wear (lena slept over,no sex) and lena decides to wait u til kara comes home, kara walks in and shees lena holding her box with a confused look on her face, so she explains why she had those stuff.)(line idea. "I-I lena i promise i can explain!"
now for the why, after seeing krypron explode kara often regrrsses to a toddler or infant in a subconscious need to feep safe and like nothing was gonna happen.
lena takes this well and hugs kara.
lena reassures kara and after a while lena eill notice kara regressing and treats her like she would any small child
