Early History
Charlotte DiLaurentis was born as Charles DiLaurentis and assigned male at birth. Charles lived with her father, mother, sister Allison, and brother Jason until she was 5 years old. One day her mother was playing in the garden with Jason and Allison was crying in her crib.

She told Allison she would get help and tapped on the window for her mom to hear and come help but she didn't as she was talking to a neighbor in the yard. Charles then took it upon herself to make Allison feel better. She told her she would run her a bath as that always made Charles feel better.

Charles took baby Allison to the tub and dropped her in. Charles didn't know what to do as Allison started to drown. Mr. DiLaurentis ran in and saw Alilison in the tub and freaked out on Charles as he thought Charles was trying to intentionally hurt Allison. According to Charlotte, as a child she always asked her mother to buy her dresses but her dad wouldn't let Jessica. Charlotte surmises that her dad sent her to Radley because of her insistence that she was a girl and not a boy, and that he knew that the bathtub incident was an accident but he just used it as an excuse to send her away.

Mr. DiLaurentis and Jessica decided to send Charles away to Radley Sanitarium. In Radley, Jessica would visit Charles regularly. Jessica bought Allison a yellow dress for Christmas when Charles was 12 years old. After that for every outfit she bought for Allison she would buy the same one for Charles.

On an unknown birthday for Charles, Jessica took both Alison and Jason out of school to attend a second cousins birthday party. However, it wasn't a second cousin but instead Charles's birthday party. The two got along very well.
