52 is Too old.    

Firstly, I doubt very much that it was an IVF pregnancy, considering they have three grown up or teenage children.

Unless her husband is not the father of the other three and was childless.

Either way, I think it's fine.
Pregnancy is possible up until the menopause happens, so, unless you want to ban over fifties from having sexy time, it's going to happen!

Good luck to her. it seems there is a lot of help and a lot of love to go around.

I don't know where you get that idea from. Whilst there are more multiple births from IVF, because most clinics implant two fertilised embryos, it is completely untrue that this 'almost always happens'.  Most IVF cycles end in failure, and the majority of women who do become pregnant through IVF have a single birth.

I am 53, and am still ovulating and having periods, so it's still entirely possible that I could get pregnant if I wanted to, or if I didn't take precautions.  I would be horrified at the idea of going through pregnancy and motherhood again at my age, but then I would have been horrified at the idea of having another child at any age    I don't think that 50 is necessarily too old to become a parent, and it depends very much on the individual circumstances. But  I do think it is better to become a parent when you are older (ie mid 30s) than at a very young age.

There are very few fertility clinics which will carry out IVF treatment on women in their 50s, but provided IVF isn't carried out on the NHS, and it's carried out in accordance with the guidelines, I don't see a problem.

Aye....good luck to her and the weans  

Think she could pull it off.

I don't know.
Of course a 52 year old can be just a good a parent - Elton John has just adopted has he not?  And if a 52 year old become pregnant naturally then it should be her choice as to whether she wishes to have the baby or not. However that is because it is nature. For a much older woman to have IVF to have a baby is not nature - it is science.

The only other thing I can add is it could get confusing at the post office claiming pension and child benefit at the same time.
