Both of my sister in laws have had third babies in the past year. They are both late thirties and already had 2 children each, a boy and a girl between the ages of 5 and 12. I think everyone thought they were 'done' so to speak so we were all a bit surprised at their announcements. I'm slightly younger and I already feel I'm finished with having children, I'm now worried I will get the urge In a few years to have another baby, how common is it to feel like you need to have another baby before it's too late? Is it normal to get broody for a last baby as you approach your forties?
