ATLANTA -- One year ago, a tree branch fell on the head of 2-year-old Tripp Halstead and crushed his skull. Tuesday Tripp's family marked the anniversary with an uplifting morning.

They took Tripp to the Georgia Aquarium.

"A year ago," said his father Bill, "a major celebration for us every hour was the fact that he was still alive."

"We spent yesterday as our grieving day," said mother Stacy. "Basically, we just spent all day crying."

That day -- the day before the anniversary -- marked a draining of emotions after a year that has seen so many. Tripp has faced surgery after surgery -- 14 in all since the accident.

But, says Tripp's mother, "For every setback, he's gone two steps forward, so we totally believe with all our hearts he's going to get better and better every day."

Today Tripp's parents say he makes noises on command and continues to gain mobility.

"We look forward to Tripp smiling for us for the first time," says dad Bill. "Just a flat-out, signature Tripp smile."

In the meantime, they have seen the smiles and well-wishes of nearly a million Facebook followers. On this morning, Stacy said, "every one of my friends had changed their profile picture to Tripp and wrote a message about why they did it, and it was overwhelming."
