The Potter Family has a lot to be grateful for these days.
Their 9-year-old daughter, Erin, is recovering from her second bone marrow transplant and is doing great.

Now, she's focusing on her recovery as her mom, Jeni, spends time working on the Champions for Hope fundraiser.
Watch above to hear more about Erin's story.
