It could be for psychological comfort. The mother may have had a difficult childhood and going back into diapers gives her a sense of security and comfort that she didn't have during those tough times.
One possible reason could be stress. Sometimes people in the ABDL community use regression as a way to escape the daily stressors of adult life, and the mother in the story might be doing the same.
Accidents during travel, as in Lily's case, can be a reason. Long trips without easy access to toilets can result in 'accidents'. Also, in some cases, if there is a lack of proper supervision or reminders during the potty - training phase, a child might need to go back to diapers for a short period to re - establish good habits.
Sometimes, physical disabilities or developmental delays can be the cause. Children with certain conditions may not have full control over their bladder function. Diapers can provide a sense of security and cleanliness for them. Also, if a child is in a situation where they can't access a toilet easily, like during a long car journey or a sports event, diapers might be used as a precautionary measure.
Sometimes in a story, it can be for convenience during a special event or situation. For example, if the girl is going to be in a place where there are no bathrooms available for a long time, such as a long hike or a remote beach trip. Diapers can be a practical solution to avoid any mess or discomfort.
One reason could be a physical illness. For example, if someone has a severe urinary tract infection that affects their ability to control their bladder, they might be put back in diapers.
One possible reason could be a medical issue. Maybe the teen has some sort of incontinence problem that has recently developed, such as a bladder or nerve disorder. Another reason might be for psychological comfort. If the teen is going through a really tough time, like severe stress or anxiety, the mom might think that going back to the familiarity of diapers could provide some sort of security.
First, accept the situation. It's important not to be too hard on yourself. If it's a medical issue, focus on getting better. For example, if you're recovering from an operation that affects your bladder control, follow the doctor's advice.
Illness could be a reason. If a girl has a serious illness like a urinary tract infection or a condition that affects the nervous system controlling bladder function, she might be put back in diapers. For example, if she has diabetes and it affects her nerve endings related to bladder control.
One reason could be a medical condition. For example, if a 16 - year - old has certain bladder or bowel control issues due to a nerve disorder or an injury. Another reason might be psychological stress that leads to incontinence. It could also be due to a developmental disorder that affects normal toileting skills.
This could be a story about a child who was potty - trained but then had to be put back in diapers for some reason, like an illness, and had an accident with pooping. It might be a common experience for parents dealing with setbacks in their child's potty - training journey.
Medical reasons could be one cause. For example, if a girl has a bladder or bowel control issue due to an illness or an injury, being in diapers full - time might be necessary.
