In April 2018, resisting being evicted from her flat, Leigh-Anne unintentionally crushed the debt collector's hand. After vacating her home, she was forced to take the bus when her car refused to start up. However, her waters suddenly broke, and she went in labour. Despite her pleading to go to St. James Hospital, Leigh-Anne was taken to Holby City Hospital's emergency department. Following some minor complications caused by shoulder dystocia, her son Kiegan was born. Ethan Hardy was left in shock when she told him that the father was Scott Ellisson, his brother's killer. After hearing that Leigh-Anne had been evicted, he helped find her and Kiegan a new place to live. Later, on the wards, Ethan visited her, and she was thankful when he told her what he did. However, when he offered to help her look after Kiegan, she declined.
The following week, Leigh-Anne visited the department's pharmacy to pick up some oral gel for Kiegan who was fighting an infection. Ethan insisted on treating him and took them to cubicles. Although he initially thought that it was just a common viral infection, upon finding a rash, Ethan realised that Kiegan had chickenpox. After Kiegan developed pneumonitis and was forced to stay in the hospital for a few days, Leigh-Anne told Ethan to leave them alone when he offered them financial support out of guilt for not saving Scott. That evening, the two reconciled and grew closer to each other. The following day, Ethan resigned from the role of acting Clinical Lead to focus on his relationship with Leigh-Anne.
