When the going gets tough, it’s nice to have a best friend to lean on.

Ayden Mosher, 3, and his bestie Aubrey Ferrell, 2, met in September in the lobby of Boston Children’s Hospital while receiving outpatient care for their respective successful kidney transplants.

The two have been inseparable ever since.

“It was like love at first sight!” Boston Children’s renal transplant coordinator and nurse practitioner Courtney Loper tells PEOPLE. “They connected with each other over a coloring book and just had this instant bond.”

Ayden, of Herkimer, New York, and Aubrey, a Milan, Tennessee, native, only see each other while in Boston for follow-up appointments, so hospital staff always makes sure to schedule the two on the same day.

“We have a lot of kids come in here and play together, but these two were something else,” Dr. Nancy Rodig, medical director of renal transplant at Boston Children’s, tells PEOPLE. “Aubrey would come out and search the hallways for him, calling his name. She would be on a mission to find him!”

The doctor adds with a laugh, “Oh, and Ayden absolutely loves the attention she pours on him. It’s so, so adorable.”

Ayden was born with polycystic kidney disease, a disorder which causes clusters of cysts to form within the kidneys.

The toddler received a transplant from his aunt in September and has been coming to Boston Children’s Hospital for outpatient care ever since.

“He used to be upset that he had to get his blood work done, and we’d say, ‘Well, Aubrey has to do it too!’ ” Ayden’s mother, Cindy Davis tells PEOPLE. “It makes him feel better to know she is going through the same thing, they benefit each other. They help each other to be strong.”

Aubrey, born at 34-weeks-old, was diagnosed with congenital nephrotic syndrome, a chronic kidney disease.

Much like her loyal pal Ayden, Aubrey received a kidney from a living donor and is on the road to recovery, showing no signs of rejecting her transplant.

“Aubrey looks at her feeding tube and the scars on her belly and knowing that Ayden has them too, it has truly bonded them,” Aubrey’s mother, Janna Ferrell tells PEOPLE. “I think in their little minds it’s comforting to know that while they’re different, they’re not alone.”

The mother adds, “Their friendship is so amazing, I’ve never seen kids connect at such a young age like that, you have to see it to believe it. I think she truly loves him!”

The moms plan to keep the kids in touch when their outpatient appointments end – a future trip to Disney World is even in the works.

“Aubrey has somebody that’s gone through the same things as her,” says Ferrell. “If we can keep the kids in contact, I know they will always be there to support each other through thick and thin.”
