I think that as you say you have "always wanted another" this is probably about more than just cute cloth diapers. If you look too hard at any of our reasons for wanting children, put them under a microscope and they won't hold up to logic, becoz IMO they are not about logic, but something else.
Kwim?
For me I have a heart and soul longing for more children, I believe being a mother is a very important part of my path and that I have a gift for it that I am *meant* to use to bring forward and nurture children.
Logically there are a million reasons why I should not have more children, why I shouldn't have had my daughter even. But logic is so obviously weak when I look at her face and hold it up against the wonder and amazement of her, and the joy and struggle this mothering path has brought for me.
I think: ask your heart if you want another child, quietly. If you long for one, do it. If you don't, don't. Coz you know it's a lot of work.

For me it's sort of the difference between going to work after being up all night with insomnia, vs. going to work after being up all night having amazing sex with your lover. The joy of it, if it is joy to you, brings an energy with it that will see you thru.
Good luck with ttc.
