Re: If you left spacing up to god (or chance)...
It would be neat if you compiled some of this data into a readable chart- it is a really interesting question.
Our first two are almost exactly 3 yrs apart.
Second and third 2 yrs 3 months apart.
Third and fourth almost exactly 2 years apart.
Fourth and fifth 2 years 8 months apart.
We exclusively breast feed and delay solids until a year. I usually get my cycle back around 16-18 months. Then, I usually get pregnant shortly after.
