If you're wondering when and how to start potty training your daughter, the latest research from childhood continence specialists has revolutionized our understanding of this important milestone. The old approach of waiting for "readiness signs" is being replaced by evidence-based methods that prioritize early, gentle learning.
Ready to start your daughter's potty journey the right way? The Riley app incorporates the latest research from leading childhood continence experts to guide you through a gentle, evidence-based approach. Discover why starting early with gradual learning beats waiting for readiness signs - and get the proven strategies that work for real families.
Rethinking Potty Training For Girls
The most significant shift in modern potty training research is viewing it as a "potty learning process" rather than a single event. Just as we teach children to brush their teeth or use a spoon through practice and repetition, potty training should be approached as a gradual skill-building journey.
There are 40 different skills your child needs to learn and put together to become potty-trained. This explains why the process takes time and why early preparation is so valuable.
When Should Girls Start Potty Training?
Contrary to popular belief, you can start teaching your child to use a potty before they stop using diapers, giving them all the time and practice they need to succeed.
The Timeline [1]:
- 6 - 9 months: Begin potty learning when your child can sit up
- 18 months: Most children are ready to master potty independence and lead parts of the process
- 18 - 30 months: Research shows your child's bladder and bowel health should stop using diapers between 18 and 30 months
This approach means starting preparation much earlier than traditional methods suggest, but with much less pressure and stress.
Potty Training Girls: Signs of Readiness
Many children, and particularly those with additional needs, will never give any signs that they are ready to potty or toilet train.
The research shows that waiting for readiness signs can delay the process unnecessarily [1]. The longer you leave it, the harder it can be for your child to learn this new skill and accept not having a diaper on anymore.
Instead of waiting, parents should focus on teaching the necessary skills through gradual preparation and practice.
The Evidence-Based 3-Step Approach For Potty Training Girls
Step 1: Preparation (From 6 - 9 months)
This foundational stage focuses on building body awareness and familiarity:
Key Preparation Activities:
- Diaper-free time: Regular short periods (up to 30 minutes) without diapers help children get used to the feeling
- Standing diaper changes: Once they can stand, involve them in cleanup and explain where waste goes
- Add sensation: If you use a disposable diaper, add a washable cloth so your child can feel wetness, as disposables instantly wick away moisture
- Bathroom vocabulary: Use consistent, positive language about bodily functions
- Address constipation: Ensure daily soft bowel movements before progressing
Step 2: Practice (From sitting independently)
From the time your child can safely sit up by themselves, they can start sitting on a potty with your help.
Practice Opportunities:
- After waking up
- After meals
- When you notice signs that they need to go
- During regular diaper-free periods
Skills to Develop:
- Communication words or signs for bathroom needs
- Getting pants up and down
- Proper hygiene habits
- Comfort with the potty environment
Step 3: Stopping Diapers (Around 18+ months)
When your child has developed foundational skills through preparation and practice, you can transition away from diapers entirely.
Success Strategies:
- Choose a stable time with no major disruptions
- Ensure adequate daily fluid intake (6 - 8 drinks)
- Use easy-to-remove clothing
- For boys, encourage sitting for both urination and bowel movements initially
- Stay consistent and avoid returning to diapers for outings
Age-Specific Guidelines for Girls
18 - 24 Months: Active Learning
With early preparation complete, most girls can now lead many aspects of the process. Focus on building independence and confidence through consistent practice.
2 - 2.5 Years: Mastery Development
Most children are ready to master potty independence and lead in many parts of the process from around 18 months. This is when many girls achieve reliable daytime control.
2.5 - 3+ Years: Full Independence
The majority of children will be capable of doing most things, including wiping by themselves when they start school. Focus on public restroom confidence and nighttime dryness.
Common Challenges and Evidence-Based Solutions
Accidents Are Learning Opportunities
It is normal to have lots of accidents at the beginning, and they are an important part of the learning process. Respond calmly, involve your child in cleanup, and gently redirect to the potty.
Regression Happens
If progress stalls, it's ok to stop, go back to the preparation stage, and start again. Check for underlying issues like constipation or inadequate fluid intake.
Fear and Resistance
Teaching your child how to use a potty and feel comfortable around wee and poo gives them a gentle journey towards being independent from diapers. Use positive language, play-based learning, and avoid pressure.
Nighttime Considerations
The age at which children become dry at night varies hugely. For some, it follows on quite quickly after achieving daytime dryness. For others, the wetting carries on after the age of 5.
Supporting Nighttime Dryness:
- Establish a bedtime potty routine
- Stop drinking one hour before bedtime
- Remove diapers during nap time first
- Avoid "lifting" (waking to use the toilet)
- Use waterproof bedding protection
Equipment Essentials
Basic Needs:
- Low potty that allows independent use
- Or a toilet seat reducer with a step stool
- Travel potty for outings
- Waterproof bedding protection
- Easy-to-remove clothing
Optional Helpers:
- Reusable training pants for transitions
- Washable clothes for disposable diapers
- Potty books and toys for motivation
Supporting Your Daughter's Success
Effective Motivation: For most children, encouraging and supporting them to be as independent as possible is the best way to motivate them. Research shows that while rewards may help initially, building intrinsic motivation through independence and capability is more effective long-term[1].
Communication Strategies:
- Use clear, confident direction: "It's toilet time."
- Avoid frequent prompting or asking
- Give specific praise for efforts and progress
- Maintain calm consistency
Working with Childcare Settings
For potty training to go well, your child needs a consistent approach to help them learn what they need to do, whether they're at home or in childcare.
Coordination Tips:
- Discuss potty training from the early stages
- Share your home vocabulary and routines
- Plan diaper-stopping dates together
- Maintain regular communication about progress

A: No. You don't need to delay potty training and wait for signs of readiness. Prepare your child by teaching them the skills they need.

Q: What about nighttime dryness?
A: This typically comes after daytime success and varies widely. Some children achieve it quickly, while others may need support beyond age 5, which is completely normal.
Conclusion
The latest research revolutionizes how we approach potty training by emphasizing early, gentle learning over waiting for readiness. By starting preparation when your daughter can sit up, practicing skills before removing diapers, and viewing the process as gradual learning rather than an event, you're setting both of you up for success.
See potty training as a process rather than an event! This mindset shift, backed by evidence from childhood continence specialists, reduces stress and increases success rates for families.
Remember that by starting the process early and gently, when the time comes to stop wearing diapers, your child will already have some skills to make this transition easier and less daunting for you both.
Whether your daughter masters independent toileting in months or takes longer, you're providing her with the foundation she needs through patient, consistent support. The key is starting early with preparation, building skills through practice, and maintaining confidence in the process - even when challenges arise.
Your daughter's journey to independence is unique, but with evidence-based strategies and realistic expectations, you can guide her through this important milestone with less stress and more success for everyone involved.
