This topic has been done before, and I always personally find the responses very hurtful. Yes, I'm sensitive about this issue, it's not nice to hear other people say it's irresponsible and selfish of me to have a child. If the OP ever read other forum posts, she'd have known that this very subject was brought up just days before she posted this one (which was some time ago).
I wasn't going to (yet again) post in this thread, but as someone who became a mother at age 42, I feel I should clarify some enormous misconceptions about women who become mothers "later" in life:
For an article to become newsworthy, obviously the scenario has to be extreme, as is the case with the article the OP mentioned. I don't know the details, so I can't comment on that specific case.
A couple of posters mentioned women WAITING until they're over 40 or even over 50. Now be reasonable, do you honestly think these women "waited" that long to have a child, as part of their Life Plan? Who sits down at age 20 and decides to start a family at 50???
For many women, a stable relationship and financial stability is something they aren't prepared to negotiate on when it comes to bringing a child into this world. Some just don't achieve this happy place at the age of 25. If a woman, for instance, tragically lost her life partner in her early thirties, it stands to reason that some may take a long time to find a partner to share their life, and parenthood with.
Although a woman's fertility marginally drops from her mid thirties, most women are, in fact, capable of conceiving naturally until they're in their late forties to early fifties. Now, we're talking IVF here, I know, the fact is that Mother Nature saw fit to design our bodies to be able to have children until that age, so it only stands to reason that women who struggle with fertility issues should be assisted up to at least that age range.
Yes, I probably won't be around to enjoy my great grandchildren, I may not see my son grow into adulthood - but then, no one, regardless of age, has that guarantee, do they? Any one of us could be hit by a bus tomorrow. Both my grandmothers has children in their 40's, one passed away when her youngest was 24, the other when her youngest was well into his forties himself.
To the PP who mentioned the teenage years and all the problems that will arise from having a teenager when you're older - how does age come to play in it? It's not as if you need to be able to physically restrain your teenager. Most people in their 60s, 70s and 80s are still of very sound mind, which is surely all you need to "deal" with a difficult teenager? How will a younger parent do it better than an older parent?
The risk of chromosomal anomalies DOES increase with age. There are also some very reliable tests that can be performed to eliminate or confirm this. And even with the significantly increased risk, the risk is still very low - it's not as if one in 10, or 20 or even 50 or a 100!!! children born to a mother older than 40 are disabled. For many women such as myself those are risks we felt comfortable taking, obviously.
But most importantly, age is a number - some people won't have the enthusiasm or energy to raise a child regardless of age. Yet others have the energy and enthusiasm but just not the inclination or dedication. I have all these things, in abundance. The women I know who have children after 40, do as well. I am sure there are many who were "old" by the time they reached 30.
But just as I can say there are some young women out there who are really silly, irresponsible and selfish and who are not fit for motherhood, I'd NEVER make that a general statement to include all, because I know that there are many who are wonderful mothers. Perhaps it would be the INTELLIGENT route to not make gross generalisations about people who become parents later in life, either.
Now in conclusion, I have to be honest - I don't know what would drive a woman in her late 50s, who already has children, to want more. Women of all ages have children for the wrong reasons all the time. I suppose it goes without saying that there will be older women wanting IVF treatment for the wrong reasons, as well.
