A little food for thought for some on this thread:
The reality is that the chance of actually conceiving a baby when you're over 40 is less than 5% chance per cycle and then the risk of miscarriage for women of that age group is very high. In fact, about 1 in 2 of these pregnancies will sadly end up in miscarriage.
That's by far the riskiest bit about being older but that still leaves 50% of pregnancies that are viable and many women do have babies in their 40's.
These little ones are absolute miracles in my opinion!
The chance of having a baby with downs syndrome does increase with age. When you're 30 it's about 0.2%, by 40 it's increased to about 1% and by 45 it's increased to about 3%.
So, even at 45 years old, there's a 97% chance your baby will not have DS.
It's also worth noting that 80% of babies with DS are born to women under 35 years old.
There is an advanced NIPT available now which tests for 70 different genetic and chromosomal issues including DS and there are other more invasive tests available too which can check with over 99% accuracy that everything is OK with your baby.
There are increased risks (between 10%-30% more likely) associated with advanced paternal age too (baby born prematurely, low birth weight, mother having gestational diabetes).
There is also believed to be a link between advanced paternal age and autism but actual findings vary between different studies - current data suggests that the overall risk of autism with an older father is around 2-5%.
Believe it or not, some studies around maternal age and autism have actually shown the number of cases to DROP after age 35!
So all of this scaremongering about having a disabled child like it's a given one you turn 40, is coming across as ignorant and unnecessary. Even with a 44 year old mother and 60 year old father, if the pregnancy is viable, then the chance of having a completely healthy baby is much higher than not.
