BROOKLINE (CBS) – An emergency dispatcher helped a mother save her toddler over the phone in Brookline.

Police Lieutenant Philip Harrington told WBZ-TV a ten-year-old boy called 911 Tuesday afternoon because his one-year-old sister was not breathing.

The boy put his mother on the phone and the dispatcher walked her through the first steps of CPR.

Moments later, the little girl started breathing again, before rescuers arrived.

She was taken to a nearby hospital, treated and released.

Harrington said the girl stopped breathing because she had fallen in the kitchen, struck her head and was knocked unconscious.
