l birth after C section?

Hello, I am a 27 year old mother pregnant with my 5th and final child. I have had 3 Natural births and 1 C section with my last pregnancy because my child was breech ed. My C-section took place June 3rd 2010 and I am due with this baby June 30th 2011. I desperately wish to do a l all natural birth like I did with my other 3 children because the father of this child is my fiance and not the father of my other children however has adopted our youngest child who is only 9 months old. This is my final child and he has never experienced a birth of a child and his dream has always been to be a father. He is a wonderful man and as much as I want him to experience this natural birth with me I also want to experience it with him for my final child. also my c section recovery from my last child was extremely horrible and painful. I could barely move decent for 2 weeks. Although my fiance is taking 3 weeks of vacation for the new baby I still want to be mobile for all my other very active boys my children are ages 6, 4, 3, and 9 months. I want to know if a VB after C Section is any more risky than if I had a C Section 2 or 3 or more years ago. Or has anyone ever done it so quickly after c section with good results or bad results. Any help/advice would be greatly appreciated.
