Meghan Hall will tell you it's good to hear the danger girl's laugh considering how bleak things were looking a few months ago.

"The chemo was really bad,” said Meghan Hall, Brooklyn’s mother. “I've never seen anything like the mouth sores. We decided July 1 to end treatment because her body was failing."

You might be asking -- how can a five-year-old with three brain tumors simply stop chemotherapy? It was all thanks to medical marijuana.

“It was like overnight that we saw this amazing turn around for Brooklyn," Hall said. “On just the cannabis she gained all of her weight back that we were concerned about, she started talking again, she started asking questions, she was singing again."

The family held a prom earlier this year, trying to build fond memories in Brooklyn’s last days. In that time they've gone on a cruise, to Las Vegas and to Meghan's brother's wedding.

What the family wasn't expecting -- was more time.

No longer able to be a patient at St Jude's Children’s Hospital, Brooklyn was taken to Golisano Children’s Hospital here in Syracuse. There, the doctors helped the family get medical marijuana.

Now, Meghan says Brooklyn’s tumors have shrunk and she's stable. It's the gift they hoped for.

"I didn't think I’d be able to see her get married or be able to do a mother-daughter day where we go do our hair, I didn't think I would be able to do any of that,” Hall said. “But now I might and that gives you hope. That's a good feeling to have because I didn't have it before."
