Little Luka White kept calm when his mother Treana Richards, 31, was crippled by excruciating pain as she got him dressed for school.
The single mum had taught Luka how to phone for help in emergencies but he realised he would not be able to find her phone which was upstairs in their home.
Despite very limited vision after being born with a rare genetic disorder he let himself out of the house and knocked on a neighbour’s door – FOUR HOUSES away.
Startled Lesley Aldridge answered in her dressing gown and the brave youngster told her: “You must come quick, my mummy’s poorly.”
She phoned for an ambulance and Treana was rushed to Yeovil District Hospital with dangerously low blood pressure.
She was given strong pain relief before being allowed to return home to Martock, Somerset later that day.
Treana was diagnosed with endometriosis two months ago – a condition where tissue that behaves like the lining of the womb is found outside the womb.
She has been told she needs a hysterectomy as soon as possible.
The proud mum-of-one said: “He’s my best friend in the whole world – he says we are a team and it’s me and him against the world.
“I’ve always been so proud of how confident and happy he is and how he takes his disability in his stride and just gets on with life.
“I’m the proudest mum in the world knowing how he stepped out of his comfort zone to go outside the house without guidance, just so he could help his mummy.
“We have a strong bond. He’s very clever and extremely loving. What he did was amazing.”
Treana said she developed extremely bad tummy pains the night before she collapsed and struggled to sleep.
She said: “By the next morning I was crippled over in agony.
“I struggled on to try and get Luka ready for school and told myself, ‘If I can just get Luka to school, I can then get to the hospital to sort myself out.’ But my body had other plans.
“After Luka had been up about an hour, I collapsed on the floor. I physically couldn’t move, it was like my body wouldn’t work.
“I couldn’t think how to get help. The pain was rippling through my body.
“I don’t know what I’d do without him.”
