MIAMI LAKES, Fla. -

The 5-month-old baby whose aunt saved his life by administering CPR a couple of weeks ago on the Dolphin Expressway in South Florida is thriving. Sebastian de la Cruz has had three cysts removed from his trachea since he stopped breathing on the side of the highway on Feb. 21.

His aunt, Pamela Rauseo, pulled over and started screaming for help before administering CPR to save his life.

Sebastian, born prematurely and with respiratory issues, is the son of Rauseo's younger sister, Paola Vargas. Vargas, a nurse at Jackson Memorial Hospital, is so grateful for her sister and happy that they know what caused him to stop breathing that day.

"It's unfortunate that he had to go through this to get to the bottom of this, but it's resolved," said Vargas.

Vargas said Sebastian's cysts could grow back but as he gets older, but they are less likely to affect his breathing.

Sebastian's family has started a trust fund to help with potential medical costs at www.babyseba.com.

Having to go through the ordeal in the spotlight has been challenging for the family, but they say they hope it highlights the need for people to learn infant CPR.
