There was some good news from the Murnaghan family Monday.

As evident in a picture posted by her mother, little Sarah can now sit up.

The 10-year-old Newtown Square girl can also stand during physical therapy.

It's been 5 weeks since Sarah underwent her second lung transplant.

Her story sparked a nation-wide conversation about organ donation.
