Three. Two sons and a daughter. They're grown now.
My eldest son was a surprise, but not the way you may be thinking. He was a baby who showed up in my life and was up for adoption, so I adopted him. Five years later I had my younger son. I was completely happy with my "set" of two little, adorable, boys; but I preferred not to just have two children. When my daughter was then born I just felt as if I couldn't ask for more - two adorable little boys and a little daughter. I left open the possibility of adopting or maybe having a fourth baby, but that didn't work out. I was absolutely happy with the three children I had. I just wasn't entirely sure I may not want one more before calling it quits. I wanted decent spacing between them all, so I could devote at least three full years to one before even thinking about having another one. I didn't start all that young, so there wasn't all that much time for both spacing AND a fourth child. :) I just would have liked, maybe, for my daughter to have a sister (but since she's grown up she says she's glad she doesn't have a sister after seeing some of her friends with their sisters. lol )
