My daughter is one month shy of 2 and a half. I am pregnant and due in June. I wanted them close enough to be friends and far enough that I don't feel like I am having TWO babies. My daughter is VERY dependent on me and I think it I got pregnant when she was 13 months that having a 2 yr old and a brand new born would just be too close, but that's just me. If you feel like you want to have TONS of kids then it would be important NOT to wait too long, but if you are just doing it to prevent fighting....that won't help. They will still fight over toys, boys, clothes...etc.
