See, I look at 30 still being quite young, well very young actually. A lot of people don't even consider children until they hit 35ish. I had my children by the time I was 30 and with my first, I was 26 and would have been one of the younger ones in the maternity ward
I could have written this myself.
I am 30 and am now done, I had my first at 26 and felt like a baby at mothers group - the next youngest mum was 32.

All of our friends are 29-32 years old and only 1 other couple has a child. The rest are getting engaged and married, and not even thinking about kids yet.

When I was younger, I thought 30 was old, now that I'm 30, my thoughts have changed. I think there's no magic number. If getting pregnant was as easy as clicking your fingers, then things would be very different, but it's not, so many factors come in to play.
I was just blessed to find the right man and have 2 healthy babies before 30, doesn't mean that works for others.
