"I aspire and work to cultivate the most nurturing environment at the centre where every child can thrive and have the best start to their lives." 

My qualifications and experience   

I have completed a Diploma in Early Childhood Education and Care, and am currently studying a Bachelor of Early Childhood Education and Care at TAFE, Western Sydney. I also have a postgraduate in Environment and Development from overseas. 

I joined SDN Mosman in the beginning of 2019 as a Room Leader in the Toddlers Room and continued working in the same role for 4.5 years. After a short break, I took the opportunity to return to SDN Mosman as Centre Director from the beginning of 2024. 

What I'm most passionate about in my role 

As an early childhood professional, it has been eye opening how integral the support of passionate educators is for children's wellbeing, learning and development. I aspire and work to cultivate the most nurturing environment at the centre where every child can thrive and have the best start to their lives. Having studied early childhood education and since taking on my passions working in early learning, I wish I had such knowledge when I was raising my three daughters. 

What I love about working with SDN 

There are challenges that come with creating an ideal learning environment for children. However, SDN’s clear vision of an “equitable world where all children thrive” makes my work more meaningful. I take home SDN’s philosophy that children are the centre of everything we do! This message aligns with my personal philosophy and my passion for early childhood education. 

At my centre I also really value my team of enthusiastic and dedicated educators who are as passionate as me! Our wonderful team have built such pure connections with the children and their loving families, and it is this very community which I love at SDN Mosman. 

A little bit more about me   

I speak Hindi and Manipuri, my native language which is one of the dialects of the Indian languages. 

As a full-time working mother and as a part-time student, it is difficult to find time for myself. However when I can, I find myself picking up books, primarily in the genre of memoirs and biographies. 

I also enjoy a game of badminton as well as table tennis with my husband on the weekends, as well as baking and cooking for my family. 

Infant & toddler educational program
Toggle Accordion

Growing bodies need movement and exercise. Growing minds need stimulus and exploration. Growing hearts need opportunities to play and mix with others.

At SDN we know that the best thing we can do for your infant or toddler is to support them to grow and develop in safe, unhurried, nurturing and challenging environments.

Because infants and toddlers are naturally curious, our centres have well-equipped indoor and outdoor areas that will keep your child moving and give them daily opportunities to explore their limits and grow their abilities.

Your child is unique and so we will devise a learning and development program within our curriculum pillars, based on what we know about your child’s interests, learning and development. Because they will always be changing and growing, we consistently review the program to ensure we are keeping up with your child’s development, providing them with the best learning opportunities.

Preschool educational program
Toggle Accordion

Get more than school-ready, get life-ready 

Getting school-ready is a journey. It begins with your child’s very first day at our welcoming early education and care centres and continues with our dedicated preschool program.

Developed by university-trained early childhood teachers, our preschool program focuses on the whole child. Children learn to make friends and work together, while gaining the skills and independence they need to thrive through the big transition to school.

Our preschool program follows an evidence-backed, play-based learning approach. Children have fun and follow their curiosity, while we weave in vital skills and learning outcomes.

SDN uses Australia’s Early Years Learning Framework to explore a diverse curriculum from science to social justice. Our days are predictable but flexible, blending structured and spontaneous learning, free play, movement and quiet time.

Our curriculum pillars are:

 Relationship and social skills

 Critical thinking and problem solving

 Early literacy and numeracy

 Health, wellbeing and movement

 Science, technology, construction and design

 Nature play and sustainability

 Creative arts

 Equity and social justice

Our centres have a transition to school program where our teachers and educators work together with local schools to prepare your child for a smooth transition, and support families through the process.

Outdoor space
Toggle Accordion

Families in our urban based centres often call our outdoor areas their “green oasis”.

SDN's outdoor spaces provide opportunities for children to enjoy themselves and have adventures. They’re safe environments for children to run, jump and yell, make mud cakes, and use their energy.

Outdoor spaces provide more than physical benefits. Even though you may think that children only play outside to have fun, they're also improving their thinking, social, and emotional skills. When they’re playing outside, they’re inventing games, learning about the world at their own pace, and figuring out social customs like turn-taking.

These are just some of the reasons SDN invests in developing new, award-winning outdoor spaces with natural designs that inspire children’s curiosity, physical play, and social play.

Centre history
Toggle Accordion

The traditional owners of the area now known as Mosman are the Kuringgai People.

SDN Mosman opened in 1944 at 33 Brierley Street, a residential house that had been purchased by SDN in 1943 and converted into a nursery school.

Mosman’s large Federation-style houses were home to professionals and artists. During the Second World War, the need for long daycare and nursery schools in the Mosman area became apparent as more women took up work, or worked for long hours.

In 1976, the nursery school’s ‘old cottage’ house was replaced with the current building, which still provides a light-filled, modern environment for the education and care of children more than 40 years later.

Since its beginnings, SDN Mosman has reflected a strong connection with local families, and supported SDN's vision and commitment to enhance the wellbeing and development of all children.

From 7 August 2023, our fees will be $218 per day for children under three years old and $199 per day for children three years and over.

SDN Mosman also offers half day sessions. Half days are $131 for 0-3 years and $120 for 3-5 years, from 9am to 2pm.

The majority of families in our centres do not pay the full daily fee because they receive Child Care Subsidy (CCS) from the government.

The subsidy you may receive through the CCS will depend on:

  • Your combined family income
  • The number of hours you work, study or participate in recognised volunteer work. This is called the ‘activity test’. If your child is in the year before school, if you are on a very low income, or if you are on parental leave, you will not have to pass the activity test to receive some CCS.

Your child will need to meet immunisation requirements and you will need to meet residency requirements to be eligible to receive the CCS.

You can also calculate what your out-of-pocket child care costs will be on the government’s Starting Blocks Child Care Subsidy Calculator.


NSW Start Strong funding - Additional Preschool Fee Relief

On top of any CCS you may receive, the NSW Government is providing additional fee relief:

  • If your child turns 4 years old or before 31 July 2024, is enrolled in a preschool program at an eligible long day care service and doesn’t receive preschool relief (also called start strong funding) from another preschool, you will receive up to $2,110 in fee relief.
  • If your child is 3 years old and not yet 4 years old on, or before 31 July in 2024, is enrolled at an eligible long day care service and doesn’t receive preschool relief (also called start strong funding) from another preschool, you will receive up to $500 in fee relief.

Find more information about the Start Strong program here. If you’ve read this information and you’re still unsure about what you’ll pay, please call us on 1300 831 445 or book a centre tour. We’re happy to answer your questions.
