A toddler who was born a preemie at just 1-pound has graduated from years of medical treatment.

To celebrate Charlie Smith's end of care, first responders and medical staff held a parade and ceremony in Powder Springs, Georgia, on Nov. 1 -- one day before his third birthday.

"He wore his cap and gown and [his nurse] Geunevah handed him a certificate," his mother, Alena Smith, told, "Good Morning America."

Charlie was born at 25 weeks gestation. Doctors gave him a 50% chance for survival and rushed him to the neonatal intensive care unit.

Smith and her husband Wendell's first son, Wendell III, was also born prematurely at 31 weeks at 3 pounds. Smith said besides having preeclampsia during her second pregnancy, she's had no serious health conditions and doctors are unsure as to why the boys arrived so early.

Because of his underdeveloped lungs, Charlie had a tracheoscopy, which was removed in 2019. He also received therapy at home, including physical, occupational and speech, Charlie's nurse, Geunevah Lafontant from Optimum Pediatric Services, told "GMA."

"This year, he's considered no longer medically fragile. He met all of his milestones and no longer required tracheotomy or gastronomy," Lafontant said.

To salute his milestones, Cobb County police and fire stations held a curbside celebration for Charlie. The sweet moment was captured on video as first responders' vehicles drove by.
