This is the heartwarming moment a two-year-old toddler with Down syndrome's took her first steps.

Mum Jessica Quarello, a content creator, captured the moment at her home in Hoboken, New Jersey.

The clip shows little Adeline taking her first steps as mother Jessica, 35, and sister Charlee, 5, watch on with joy.

Jessica has been documenting Addie's journey on social and is a full-time advocate for disability awareness.

After being posted on TikTok, it quickly went viral gaining over 1,00,000 likes and 6,500,000 views.

"I knew it was a special moment, but I didn't realize just how viral it would be.

"It is so amazing to know we live in a time where disability and small feats are celebrated. It means the world to our family!

"The reaction was unbelievable, it felt like the whole world was cheering on our girl right with us!

"The video tugs at heartstrings because you can really feel the pride and see it in my face but also hear it in big sister's response too!"

Jessica highlighted how children with Down syndrome have their milestones delayed compared to other children.

That's why this moment was so special and deserved such an enthusiastic response.

"Having a child with Down syndrome means that all milestones are a bit delayed.

"Walking was a huge milestone for Adeline due to her diagnosis of hypotonia which is common for individuals with Down syndrome.

"Hypotonia is a condition that creates low muscle tone.

"Seeing Adeline standing on her own like that was such a huge moment.

"Adeline has taught us all to 'celebrate big the small' and these moments that most of us take for granted are enormous achievements for our baby girl!"

Quarello spoke of Addie's journey and how it has been a positive experience her family.

"When Adeline was born in July of 2020, we experienced a birth diagnosis.

"We had no idea our baby would be born with Down syndrome so there was a lot to deal with post-birth.

"We were scared and overwhelmed and terrified of the future.

"Luckily, we discovered very quickly on our journey with Adeline that Down syndrome was nothing to be afraid of, in fact, it is something to be celebrated.

"As her Mother, I feel extra lucky to get to parent such a remarkable child.

"I see how hard she works to achieve her goals and she has provided me with a beautiful new perspective on life.

"She has changed us all for the better."

After becoming a parent of a child with Down syndrome, Quarello co-founded an advocacy platform "dedicated to spreading the joy of disability motherhood."

She explained: "It was important to me to advocate for my daughter in the best way I knew how which was shouting her worth and building community.

"Advocacy for me is all about visibility.

"We typically fear what we don't understand which is why I am so dedicated to educating the world on all that Adeline IS capable of, not incapable of.

"When we started Extra Lucky Moms, it was to create a community of people where everyone was welcome.

"We wanted to talk more about what we all shared rather than separate us by our disabilities.

"We have loved celebrating what DOES make us different and learning so much about everyone in the disability community."
