In my mothers' group when I had DD there was one 40 yr old pg mum-to-be who had successfully conceived through IVF (first baby, DH 50). Another had conceived naturally at 42 after several m/cs (also had a 12 year old DD). Last year, one of my friends had her third DD at 40, also has a 5 and 7 year old.

In our area, having a baby at 40 is common. Me having a baby at 29 was not at all common. At 34 I'm just hitting average.
