If you are thinking about having a child, talk it over with your partner. If you're not ready, determine why you're not. Many people are just scared to make that commitment - to be responsible for another life. There are no guarantees in life, and many of the factors affecting older parents can also affect parents at any age. The ability to love and take care of a child is certainly a good prerequisite for becoming a parent.
Midlife parenthood has so many rewards that people feel the benefits outweigh the risks.
It's easier to relax and have fun with your children when you know you have the resources to care for them. Age also brings self-knowledge and control, and you are less likely to project your own longings onto your children to fulfill your needs. Older parents can still maintain their careers if they choose because they have the resources to afford good child care - something they might not have been able to do in their 20s. And of course, the maturity level of older parents is a definite asset. They are past feeling like kids who still need to be parented and can move right into a positive parenting role.
