Becoming a mother over 40

As you get older, trying to decide whether you want children or not becomes more pressing as we become aware of the limitations of our biological clock.   I see a number of women clients who are in their late 30's and early 40's who have additional concerns/worries about whether they would be able to cope with motherhood.  I found this website Mothers Over 40  aimed at mothers and those thinking about being mothers in mid-life - I think it's important to see positive examples of people who have taken the decision to be mothers outside of the 'normal' age bracket.
