I got preg with my second when my first was 9/10 months old. At that point my scar was still pretty tender/numb but it didnt bother me during the pregnancy at all. I got preg with my third when my second was also 9/10 months old. My scar felt fairly normal at that point, but it did bother me during the pregnancy because I had an internal adhesion. That wasnt anything dangerous, just painful. As you know my incision is having major issues healing this time because of all the scar tissue, but the Dr says the time between doesnt matter in this situation, just the fact Ive had 3 c sections. Altho overall my body feels unhealthy and worn out so overall I do think thats slowing my recovery some. I think anything after 9-12 months is fine to ttc, but waiting longer if you plan to do a vbac wouldnt hurt. Also I just want to add, I LOVE having my kids close together. They are best friends and have the greatest time together. They only downfall is they gang up on me and plan trouble together. lol
