planning pregnancy post c section

I have a 2 month old and had a section. In an IDEAL world we would like 2 kids. General advice, I believe, is to wait 12 months. I know people who have had very close consequetive sections - no issues bar back pain for one and pelvic pain for another and others who had no issues but the norm. Plus you can have those issues anyway. The person with the biggest problem had 2 sections within a year! I wouldn't quite fancy that now! Given my age my gp suggested 6 months so as not to leave it too long so reckon we will err on the side of trying sooner rather than later but would like to hear the experiences of others. And naturallywe realise that we may not get lucky again either way. Blessed to have one of course but would like to try once more if possible. I would much rather wait 2 yrs but age is against me.
