Yandere Batfamily x neglected!reader but...
During patrol reader gets hit with a de-aged serum, gas or whatever you guys would think.
Forcing the Batfamily to take care of baby reader.
Only for them to realised how they don't awfully remember connecting reader like this.
Realising that Reader must've had to grow up like a tall child because they forgot reader is still a kid. Yet, Reader acts so so much grown despite being the normal child.
After the effects are off, Reader is weirded out about how their family wants them.
And when the Batfamily realised that sooner or later, Reader will drift away...
But that won't do.
Reader is their baby, the littlest one. Reader just need a realization that they still need to be taken care of, even if the Batfam inject something in the reader's body without their notice.
Even if Baby!reader cries for their teenager life every night. The Batfam will always be there to comfort their baby sibling! Feeding them, bathing them, taking care of them! Their baby! <3
