Annegret
Raunigk has added three boys and a girl to her huge brood after they
were born prematurely on Tuesday in Berlin, German media reports.
The
four new arrivals were delivered by cesarean section after 26 weeks,
and are named Neeta, Dries, Bence and Fjonn according to RTL.
Her decision to conceive again was controversial, even within her own family.
Earlier this year her tenth child spoke out against her decision to have even more children.
Her son Velten Raunigk, 27, previously said: "I don't think it is a good thing for mum to be having even more babies."
The chemical industry executive spoke out a day after his mother
appeared on television to speak about her decision to have the children
after spending £15,000 on IVF treatment in Kiev, Ukraine.
Velten was the first of the clan to speak out against his mother.
He said that his youngest sister Leila, who turned ten earlier this
year, is already bullied at school because of her "grandma mum" and he
and his siblings fear they will be left to bring up the quads if
anything happens to his aging mother.
He said the family learned about her pregnancy after a family gathering earlier this year.
"I
remember mum drank no wine and she seemed to be wearing extra-wide
clothes," he said. "I had a feeling even before she told us."
He said his youngest sister Auda, 22, broke the news to him.
He added: "I learned she had gone abroad and was artificially inseminated and was expecting quadruplets."
"My youngest sister Leila is ten," he continued. "I know she is bullied at school because her mum looks like her grandmum.
"How will that work with quadruplets?"
His
father Ulrich died at 63 in 2008. He had nine children with Annegret,
two others were born earlier and fathered by other men.
He went on: "Shortly before the reunification of Germany my parents separated.
"He took the eldest five with him but he didn't stop caring for us others."
Two other men sired the two other children which make up Annegret's enormous tribe.
But
although Velten criticises his mother's decision, he said she has
always played her motherhood role well, adding: "Whenever we had
problems she was always their for us.
"After the break with my father she flew us all off to Mallorca for a beach holdiday.
"The two weeks I spent there was the best experience of my childhood years.
"Despite
disagreeing with her, if she needs help and support in the future, we
will be there for her. Our family sticks together."
