"WE went to bed and the next thing we woke up in the middle of the night as grandparents!"
That was the stunned comment from proud nanny and grandad Mark and Marrion Thorpe whose daughter Heather gave birth within five minutes, alone in her bedroom, at their Chelmsley Wood home.
The mum-to-be had gone to bed at 11pm the night before. She was in some discomfort but her waters had not broken. The 23-year-old then had a huge contraction at 3.55am and baby Jonathon was born five minutes later weighing 5lbs 7oz.
"I went to bed but I couldn't sleep and then I had this urge to push," said a delighted Heather.
"I shouted for my mum and before my mum and dad got to the bedroom, I had already delivered. Their faces were a picture!"
Heather's parents called for an ambulance after the birth and mum and baby were taken to Heartlands Hospital where the pair stayed for three days.
The super fast birth happened in the early hours of November 22 and little Jonathon is thriving despite being born ten days early.
Heather, who lives in Sheepclose Drive, added: "What's nice is that I was born on a Thursday, so was my brother and now my son. And it was the ambulance man's birthday!"
Marrion, aged 48, said: "He's beautiful. He's well behaved and gaining weight.
"We are very proud grandparents and I still can't believe he was born in this house."
