How does one know when your family is complete? We are in the fortunate position of being able to afford a fourth child, but I am 37 and time is getting on so I feel I must make up my mind in the near future. We have three healthy children so I feel that I don't want to press my luck. My husband says it's my decision and supports me whatever I decide. Is it a feeling you get when you know that your family is complete or is it a more practical decision?
