I kept seeing a manga or a novel with the protagonist reincarnated as a baby, with full memories of past life. The family she joined are villains and she is worried(?) or maybe happy(?) to be apart of this family. In the write up they say the villainous family starts acting all lovey-dovey, and cutesy toward the baby. Anyone? I'm sooooooo tired of searching?
I didn't remember the multiple past lives, but it is definitely Baby Raising A Devil. Thank you! Yay!!
