Baby Grant Weaver, swept away in Puntledge river, smiling again

The baby boy rescued from the Puntledge River in Courtenay, B.C. last week remains in hospital, but has been steadily improving.

And there are new signs of hope — posted online by Grant's father, Doug Weaver, who has been giving updates on his son's condition on Grant's gofundme web page.

Two days ago, Doug reported the seven-month-old had opened his eyes.

Within the last 24 hours, Doug says the baby has been able to follow along with his eyes as the family read to him. Late yesterday, he began to smile.

"We were able to squeak a couple of smiles out of Grant today," Doug wrote Friday.

"Wearing the mask to assist in breathing is uncomfortable for the little guy to say the least. Hopefully in a few days the medical team will be able to remove it. Following that I'm told, he's out of the ICU ward and off to another one on the floor above. He's a strong kid!"

Grant Weaver has been in critical condition at BC Children's Hospital since Jan 30, when he was recovered from the Puntledge River in Courtenay, B.C. 

His mother Veronika, who was pulled from the same river an hour later than her baby boy, died the following day. It's still unclear how Grant and his mother ended up there.

Investigators found the mother's car parked near the bridge.

The BC Coroner's Service said earlier it is investigating all potential causes ranging from postpartum depression to a tragic accident.
