Adrian's father, whose pregnant wife stayed behind in Trinidad on doctor's orders, said that while he's hopeful his son will get the surgery he needs, every passing day poses new challenges.
For one, as Adrian grows and gains weight, any potential fall becomes that much more dangerous, said Raheal.
"As Adrian gets bigger [a fall] will be a much stronger impact on his heart," said Raheal.
Similarly, Adrian's doctor, Rosenkranz, said that the type of intricate surgery Adrian needs becomes more challenging as the child ages.
"It's much easier if this surgery is taken care of, from a technical point of view, the younger the child is," said Rosenkranz. "Their [chest wall] is more flexible then."
And while Raheal and Rosenkranz say that Adrian isn't in any pain, his father believes that the toddler is starting to realize that he is different from his peers.
"He saw another little girl lift up her shirt and saw that she does not have what he has," said Raheal. "It made him curious."
"He just kept putting his hand over his heart," he added.
