I am considering to have another child. However, I think I am too old to have (I am late 30s). What is the age range that I should stop considering getting pregnant?

Your energy level will start to decline once you cross 40. I have a friend who gave birth at 44. One of her key concerns right now is how to maintain her looks. She doesn't want to stand out in the wrong way when the time comes for her son's Primary 1 enrollment (she will be 51 then). Kids actually do compare how their mothers look. Not kidding!
