Molly, her parents, brother and three sisters, are in Memphis, Tenn., where doctors at St. Jude's Children's Research Hospital can offer treatments unavailable in B.C.
Physicians were forced to put Molly into a medically induced coma Sunday after her condition deteriorated late last week and she suffered numerous seizures.
In a tweet Monday morning, the girl's father, David Campbell, said specialists hope Molly is stable enough for an MRI later in the day to help pin-point the cause of the seizures.
In a post on Friday he wrote the family misses "our talkative, bubbly little girl and we feel she is slipping further from us."
Molly won hearts in December 2011, when, at just 28 days old and just two days before Christmas, she was diagnosed with cancer of the white blood cells but managed to fight the disease into remission for a year until relapsing last November and being sent to Memphis for intensive chemotherapy.
