Emily Ruben: Diane Blood is now looking forward to spending some quiet time with her son

She said Liam's premature birth by Caesarean section on 11 December was "wondrous and unbelievable".

Mrs Blood, 32, told BBC One's Breakfast With Frost programme that Liam was "doing great".

"He was in special care for around 10 days, but once he started getting better he was great and there was no stopping him.

Diane Blood: All my thoughts are with Liam at the moment

"For any mother the birth of their child is something that is wondrous and unbelievable and I certainly thought that when he was born."

Speaking from her home in Worksop, Nottinghamshire, she said she was overwhelmed by support from well-wishers having received 500 cards from around the world since the birth in Sheffield - but had no plans for another child.

Diane Blood fought for three years to use her husband's sperm

"It's something that is medically possible, but it's not something I have got in mind. All my thoughts are for Liam."

Mrs Blood fought for the right to have the child for three years after her husband Stephen died from meningitis in 1995.

Sperm had been taken from Stephen while he was on a life support machine.

But without written permission, the Human Fertilisation and Embryology Authority ruled she could not be legally inseminated.

Eventually the Court of Appeal ruled in February 1998 that under European Law she had the right to use the sperm.
