BERLIN (AP) – A 65-year-old German mother of 13 is getting ready to give birth again – this time to quadruplets.

Bild newspaper reported Monday that Annegret Raunigk, a Berlin schoolteacher who is due soon to retire, is expected to give birth to the four babies in two months.

She already has children ranging in age from 9 to 44, from five fathers. This time, Bild reports that donated eggs were fertilized and implanted at a clinic outside Germany.

Raunigk says she decided to become pregnant again because her 9-year-old daughter wanted a younger sibling.

Medical professionals have criticized her decision, but Raunigk says she is not worried.

She is quoted as saying: “They can see it how they want to, and I’ll see it the way I think is right.”
