It could be her family members. For example, her parents or siblings might be very concerned about her health and constantly trying to persuade her to take care of herself. They would be the ones using their love and concern to try and break through her stubbornness.
Well, perhaps the plot could revolve around Amy Fleming being sick with some kind of illness, maybe a fever or a more serious disease. And her not listening could be related to her being stubborn about getting proper treatment. For example, she might be so focused on taking care of her animals or something else she loves that she ignores her own health needs.
Definitely Ty Borden. He and Amy have a special relationship, so he would be deeply concerned about her illness. He could be the one running errands, getting medicine and making sure she has everything she needs. Georgie could also be a main character. She could be helping Lou with the ranch work and also spending time with Amy, telling her stories to keep her spirits up. And then there's Spartan, Amy's horse. Spartan could be acting strangely because he senses something is wrong with Amy, and his behavior could be a part of the story as well.
One possible story could be that Amy Fleming uses her skills and knowledge (assuming she has some relevant skills in the original context) to take care of the sick little kid. She might bring the kid some warm soup, read stories to comfort the child, and call a doctor if needed.
One idea could be that Amy Fleming has caught a strange illness that is affecting her ability to take care of the horses. Her friends and family rally around her, trying different remedies. Another could be that she gets sick while away at a horse show and has to rely on new acquaintances to help her get better. Maybe she contracts a virus that makes her weak, but she still tries to be involved with the horses in whatever way she can, like giving advice from her sickbed.
Another aspect could be the relationship between Amy and the baby's father. If he is present, they might have different reactions to the situation. He could be overly protective or, on the other hand, struggle to deal with the added pressure. The fanfic could also involve some conflicts that arise due to their different viewpoints on how to handle the pregnancy while she is sick.
One possible plot could be that all of Amy Fleming's friends come to visit her while she's sick in bed. They bring her get - well - soon gifts like flowers and homemade soup. They then sit around and share stories to cheer her up.
The neighbors could also play an important role. They might be the ones who notice something is wrong first and inform Amy. Later, they could bring over home - made soups or offer to babysit other children if Amy has more than one, so she can focus on the sick child.
Perhaps the fanfic focuses on how Amy Fleming deals with her own emotions while her kid is sick. She could be feeling helpless, scared, and guilty. The story might show her journey of coming to terms with these feelings and finding strength within herself to take care of her child.
The plot could be that the sick little kid is lost and alone when Amy Fleming comes across. Amy decides to help the kid get well. She first tries to find the kid's family while also taking care of the kid's illness. Maybe she gives the kid some medicine she has on hand if it's suitable.
