Why Swimming More Than Once a Week Matters
At Kapiti Learn To Swim, our Diaper Dolphin Programme is built on the philosophy and teachings of Rob McKay, a world-renowned infant aquatics educator whose child-centred approach has influenced learn-to-swim programmes around the globe.
In 2011, Mandi McKenzie spent two months in Florida training in the Rob McKay methodology and brought this unique approach back to New Zealand. At the time, Kapiti Learn To Swim was one of the first swim schools in New Zealand to offer this style of attachment-based, child-led aquatic education.
More than a decade later, these principles remain at the heart of everything we do.
One of the key foundations of the programme is the understanding that children learn best through frequent, positive experiences in the water.
More Than Just Swimming Lessons
Many people assume swimming lessons are simply about teaching a child how to swim. In reality, every activity, game, song, and skill within our programme has been carefully designed with a specific developmental and water safety purpose in mind.
Our goal is not simply to create swimmers.
Our goal is to create children who are confident, capable, and safer around water.
Throughout the Diaper Dolphin Programme, children are learning essential water safety and survival behaviours such as:
Turning back towards safety
Reaching and grabbing for an edge
Climbing independently from the water
Developing breath control
Building propulsion through kicking
Understanding body position and orientation in the water
Learning recovery skills
Developing confidence when submerged
Every skill has a purpose. Every activity has a learning outcome.
The repetition of these skills helps children build automatic responses that may one day support them in an unexpected water situation.
Progression Through the Diaper Dolphin Programme
One of the most important aspects of the Kapiti Learn To Swim philosophy is that children progress when they are developmentally, emotionally, and physically ready—not simply because they have reached a certain age.
While each level has a minimum age requirement, age alone does not determine promotion. Children must also demonstrate the skills, confidence, and understanding required for the next stage of learning.
This child-led approach is at the heart of the Rob McKay philosophy. Skills learned through confidence, readiness, and positive experiences are retained more effectively than skills introduced before a child is prepared for them.
Every child develops at their own pace. Some children may reach milestones quickly, while others may need additional time, practice, and repetition. Both pathways are completely normal.
Our goal is not to move children through levels as quickly as possible. Our goal is to build strong foundations that create safe, confident, and capable swimmers for life.
Diaper Dolphin Beginner
In our Diaper Dolphin Beginner level, children are introduced to the foundations of aquatic confidence, trust, and breath control through gentle, child-led learning experiences.
To be considered ready for progression, swimmers should:
Happily submerge underwater for approximately three seconds
Demonstrate a propulsive kick while submerged
Show confidence and comfort with the skills being taught
Meet the minimum age requirement of 12 months
These early skills help children become comfortable underwater while laying the foundations for future swimming and self-rescue skills.
Diaper Dolphin Stage 1 (DDS1)
As children progress into DDS1, the focus shifts towards increasing independence and practical water safety skills.
To be considered ready for progression, swimmers should:
Complete a 5–7 second underwater submersion with a propulsive kick
Independently reach for, grab, and pull themselves up onto the pool wall
Independently climb onto the teaching platform
Consistently demonstrate confidence and understanding of the skills
Meet the minimum age requirement of 19 months
At this stage, children spend a great deal of time practising turning, reaching, grabbing, climbing, and orientating themselves in the water.
These are not random activities. They are carefully designed water safety behaviours.
The intention is that if a preschool child unexpectedly entered the water, they would begin developing the instinct to turn towards safety, reach for a surface, grab hold, and secure themselves if possible.
Diaper Dolphin Stage 2 (DDS2)
In DDS2, children begin combining their foundation skills into more advanced aquatic movement patterns.
Swimmers begin learning:
Paddle arms
Independent propulsion through the water
Pop-up breathing techniques
Rolling and flipping onto their backs
Maintaining an airway while recovering
Learning to roll onto the back is a particularly important milestone. It allows a child to access air, regulate themselves, and continue moving safely in the water.
These skills form part of a carefully planned progression towards independent swimming and lifelong water competence.
Changing Family Life
Since introducing this programme in 2011, we have seen significant changes in family life throughout Kāpiti and across New Zealand.
Today, many households are balancing two working parents, busy schedules, and increasing demands on family time. As a result, fewer families are able to access swimming opportunities outside their weekly lesson.
We completely understand these realities and recognise that modern family life often involves balancing work, childcare, school, sport, and numerous other commitments.
However, it is important to understand how this can influence a child's progress within the programme.
Why Additional Swimming Makes Such a Difference
Swimming is not only a physical skill—it is also a sensory, emotional, and neurological learning process.
Every time a child enters the water, they strengthen neural pathways, build confidence, improve body awareness, and reinforce previously learned skills.
A weekly lesson provides an essential foundation, but regular practice between lessons often accelerates learning considerably.
Children who experience the water multiple times each week generally:
Retain skills more effectively
Build confidence more quickly
Develop stronger muscle memory
Become comfortable in a wider range of aquatic environments
Progress through programme milestones sooner
Develop stronger water safety responses
The lesson teaches the skill.
Practice helps the child own the skill.
Because our programme is based on readiness rather than attendance or age, regular exposure to the water can significantly support a child's development.
When swimming only occurs once per week, children can still make excellent progress. However, naturally there are fewer opportunities to reinforce learning and build confidence. As a result, reaching some of the milestones within the Diaper Dolphin Programme may take longer than it did for families who were able to swim more frequently.
This does not mean a child is falling behind.
It simply means their learning journey may take a little longer—and that is perfectly okay.
Every Water Experience Counts
The good news is that practice does not need to happen during a formal lesson.
A visit to the local pool, a swim at the beach, practising familiar activities from class, or simply enjoying playtime in the water with family can all support your child's development.
The goal is not perfection.
The goal is creating positive aquatic experiences that build familiarity, confidence, enjoyment, and safety.
More Water, More Confidence
Everything outlined in this document leads to one simple conclusion:
Children who spend more time in the water generally develop greater confidence, stronger water safety skills, and progress more efficiently through the Diaper Dolphin Programme.
As swim teachers, we see first-hand the difference that regular exposure to water makes. Skills become more familiar, confidence grows, and children have more opportunities to practise the important water safety responses that are embedded throughout our programme.
While children can absolutely make progress attending once per week, we know that additional water time can significantly improve confidence, skill retention, and overall progress.
For this reason, Kapiti Learn To Swim is introducing a new initiative designed to encourage more water time for our swimmers.
Second Weekly Lesson – Just $10.50
Families currently enrolled in a weekly lesson will have the opportunity to enrol in a second lesson each week for just $10.50 per lesson.
The purpose of this initiative is not to rush children through levels or create unrealistic expectations. Rather, it is to provide more opportunities for children to:
Reinforce skills learned in class
Build confidence through repetition
Strengthen water safety responses
Improve muscle memory and body awareness
Become more comfortable with submersion
Develop stronger propulsion and swimming skills
Reach developmental milestones when they are genuinely ready
The additional lesson helps bridge the gap between weekly classes, allowing children to revisit skills while they are still fresh and continue building confidence through positive experiences.
Whether your child is learning to happily submerge for three seconds, independently climb onto the wall, turn and reach for safety, roll onto their back to breathe, or develop paddle arms and propulsion, additional practice helps transform these skills from lesson activities into instinctive responses.
In a country surrounded by rivers, beaches, lakes, and pools, water safety is not simply another extracurricular activity—it is an essential life skill.
We believe this initiative reflects the very reason Kapiti Learn To Swim was founded: to create safe, confident, capable swimmers through regular, enjoyable experiences in the water.
For families who are able to take advantage of this opportunity, a second weekly lesson may be one of the most valuable investments you can make in your child's aquatic education and long-term water safety journey.
Our Commitment
At Kapiti Learn To Swim, we remain committed to the principles that inspired our programme more than a decade ago: connection, trust, confidence, safety, and learning through joyful experiences.
Whether your family swims once a week or several times a week, we will continue to support your child's individual journey.
We simply encourage families to take every opportunity they can to enjoy the water together, because every positive experience helps build a safer, stronger, and more confident swimmer.
When children have regular opportunities to practise, the skills become more than lesson activities—they become instinctive responses. And in a country surrounded by water, those instinctive responses can make all the difference.
