I've had 2 CS and I waited till DS was 14 mths before falling PG this time (my babies were 7 1/2 pounders), so a 2 year gap btwn births. I was PG 8 mths after my first CS and had a gap of 17 1/2 mths btwn births. I would have had no hesitation in having a smaller gap this time but didn't fancy 3 kids under 3. 3 kids under 4 I can deal with as the oldest will be in kindy.

As for the number of CS, my ob said that the record is 11 CS for 1 lady . I don't really think there is a set limit, I'd say it would depend on your individual circumstances.
