How soon after csection can i attempt to ttc? baby is 4 months and we want 2 more. why would i need to wait 'x' amount of time to ttc after csection?

After C/S: I understand your time constraint. In general it is best to have your pregnancies no closer than two years apart, whether you delivered vaginally or by c/s. If you want to try to deliver vaginally after a c/s, two years apart is recommended. Studies show less trouble and more success. That said, at 37 the sooner you have the next baby the better. You might compromise and start at 6 months after.
