There's an interesting awareness campaign doing the rounds right now, fronted by Kate Garraway.
Kate, who had her children at age 38 and 42, is backing the campaign to get women to consider having children earlier.
I had my children at 31 and 34, and I've always been of the opinion that whenever you have a family, if you have one, that is the right time for you.
But I can sort of see where they're coming from with this campaign. As women have increasingly had babies at an older age, biology has not caught up.
Just because more people are having babies in their forties doesn't mean that we're all becoming more fertile in our forties. You're still at your most fertile in your mid-twenties. At 35 you're half as fertile as you were at 25. At 40 you're half as fertile as you were at 35.
How many people are truly emotionally ready to have a baby in their early twenties? But then again, if you start early you get it all done and dusted quickly.
There's really no best time to have a baby, there are positives and negatives at all ages.
Though personally I think I prefer a bit later rather than sooner. Possibly skipping straight to granny stage, with a whole lifetime of experience and wisdom behind me.
The problem with this campaign is that it's basically a fallacy. Not that many people really get to choose exactly when they give birth. And it's not just about fertility, there are many other issues to take into account too.
But still, it's got people talking, which I guess is the whole intention.
