Boy, 4, saves mum's life calling 112

The little boy made the call and told operators his mum was 'not very well', and was able to give his full address when asked.

Phone staff asked him if he was able to reach the door handle to let them in when they got there, and he said yes.

He even put the phone to his mother's ear so they could hear her and get an idea of what was wrong with her.

She had collapsed on the floor, unable to move, and was in a confused and delirious state.

It turns out the mother has a chronic medical condition, the nature of which has not been revealed.

Meanwhile, her son picked up his four-week-old baby sister and comforted her as she was crying.

In the post-call suggestions, the mother said staff ought to have kept her son on the phone for longer to 'distract' him, given that he rang them back up to 10 times to ask if the ambulance was coming.

The 112 staff said they would take note, and praised the family for teaching their child how to deal with an emergency at such a young age.

Paramedics reached the house – in an undisclosed village of 7,000 inhabitants in Castilla y León – without incident, thanks to the little boy's accurately giving the call centre staff his address, and he let them in himself.

His mother was taken to hospital, but discharged shortly afterwards.

Emergency staff say they were 'extremely impressed' with the child's actions, and said he remained completely calm throughout.
