Some really adorable images have emerged showing a newborn holding his mum’s coil which failed to prevent a pregnancy.

Paula dos Santos Escudero Alvarez, 32, gave birth to Bernardo on July 4 in the Brazilian city of Rio de Janeiro.

The mum had been using birth control, called an intrauterine device (IUD) known as the coin, for three years.

But she still fell pregnant anyway, which is extremely rare, as the device tends to work for between five and ten years.

Bernardo was born healthy at 32 weeks, weighing just over 3kg (7lbs).

And shockingly the mum’s first child, Gabriel, was also born when she was on the pill.

Birth photographer Michelle Oliveira described Bernado as a “miracle”.

She said that when her second baby was born the coil was removed and given to him to hold.

The tiny boy clutched it in his hands as he laid on his mum for the first time.

Michelle said: “The IUD was placed in his little hand to represent his arrival.

“The baby was born, the IUD was removed straight away, and the doctor placed it in his little hand.”

The photographer wrote on Instagram that “there are no barriers that stop a miracle”.

She added: “This arrival was beautiful and exciting. What a joy to share this rarity! Welcome, Bernardo!”

According to the NHS, IUDs are more than 99% effective at preventing pregnancy.

The contraception works by releasing copper that makes it difficult for sperm to survive or for a fertilised egg implanting.
