A mum has given birth to a whopping 14lb 15oz baby - believed to be the third biggest newborn ever in the UK.

Cherral Mitchell, 31, needed two midwives to haul out big Alpha before he left staff shocked when he weighed in at more than a stone.

He's since been nicknamed 'Baby Hippo' and 'Butter Bean'.

And the big little one was also a surprise - born despite Cherral getting the contraceptive coil before he was conceived with electrical engineer husband Tyson, 35.

Cherral, who has three more kids, said: "We didn't think he was going to be that big.

"Everyone kept laughing when his head came out. My husband Tyson was like 'oh my God he's chunky'.

"There were two nurses pulling - one was trying to push him down to get him out.

"The nurses said it had to be the biggest baby and were on their phones Googling.

"He’s a bit of a pumpkin baby with it being so close to Halloween."

Alpha, who was born at 38 weeks on Thursday, is believed to be the UK's third-biggest baby with the current record holder being 15lb 8oz Guy Carr, born in 1992.

The second biggest is 15lb 7oz George King, who was born in Gloucester in 2013.
