Did you know you were ready to have a second child? Like did it hit you like a tonne of bricks? Did you just decide to ttc again and it happened?

I have an almost one year old DD whom is the absolute light of my life. We always said we would ttc again when she was around 12 months (took us 11 months to get pregnant last time due to annovulation) but now that time is fast approaching, I don't know if I'm ready. I know for a fact I want more kids, 3 ideally, but I am so scared of going through the newborn stage again. I finally feel like DD has a bit of independence, which is lovely, and she is full of character and charm, our days really are generally filled with love and laughter!

I'm also scared of ruining my relationship with her. Irrational, I know, but I devote so much love and energy into her, it feels cruel to introduce another baby to take some of that time away!
But, by waiting a while before ttc, I'm worried that as DD gets older, I am less likely to want to go through the difficult newborn stage again.

I think my main fear stems from having a chronic non-sleeper for the first 9 months of her life. Whilst she is now a wonderful sleeper, 12 hours at night and usually one 2 hour day sleep, the torture of the sleep deprivation is very close to mind.

Any stories, advice, encouragement?
