Charlotte Medlicott, 20, from Telford, Shropshire had been advised by doctors to abort two of the babies to give the others a better chance of survival, but now, six months after their birth, the four little girls are fighting fit.
Miracle tots Evelynn, Gracie-Lou, Rosaline and Amalia-Rose were christened this weekend, and their proud dad said their arrival had been a 'shock to the system'.
Mark Connaughton, 26, said: "To find out you're having one baby is enough of a surprise but four is very different!"
Charlotte had been told that her polycystic ovaries - a condition which can cause infertility- could rule out pregnancy. Despite this, the quadruplets were conceived naturally - to their mum and dad's surprise!
Charlotte told reporters: "They are all very well behaved babies. They cry when they want something but then they just go back to sleep. There's always one who wants something, though."
She added that her little girls will undoubtedly have some fallings out when they get older - and are already competitive:
"You can tell the girls will argue when they are older – they already have little tiffs to get more attention!"
Aw, what a lovely story. Huge congratulations Charlotte and Mark!
