Eloysa Vasquez, 38, stands just three feet tall and has to use a wheelchair because she suffers from a condition that makes her bones soft and brittle. But last month baby Timothy was delivered eight weeks prematurely by Caesarean section.
He weighed 3lbs 7oz and did not inherit his mother’s genetic condition, Type 3 osteogenesis imperfecta.
She weighs just two stone and nine pounds.
There was little room in her tiny body for a foetus to grow and she had had two miscarriages before the successful birth at Stanford University’s Lucile Packard Children’s Hospital in California.
According to the university, only one in 25,000 to 50,000 births are to a mother with the disorder, and even fewer involve mothers with the severe form Mrs Vasquez has.
Obstetrician James Smith said Timothy’s birth was a one-in-a-million event.
“We just took it one day at a time. We had a lot of people praying for us. We just believed ... and here we have our son,” Ms Vasquez said.
