What is the best number of children?

I believe that for everyone we all want a different amount of children and for some , don't want any and I don't feel that any choice is the wrong reason . I have five right now and would maybe like to have more but not sure if I would be able to because of medical problems , I would love to adopt but would never be able to afford the adoption process as it is so expensive . But like you , I love children and always did . I used to say when I was younger that I only wanted two but as I got older I realized that I love having little one's in the house and wanted more and would have had more had I not had so many problems and could have carried them all to term . But I love the five I have with all my heart and they will always be very special to me weather I can ever have more or not .
