Does/did anyone else feel differently ttc the second time around?

The first time I was soo excited, we started ttc right before our wedding. It's all I ever thought about! I got pregnant really quickly, we were very lucky!

We've just started ttc#2 and it feels so... anti climatic. No big lead up, no obsessing. I think part of the reason is I'm so busy working and caring for DS, I just don't have time to obsess! Plus I'm majorly over analyzing what the "ideal" age difference is, whether we should wait a bit longer (if it happens quickly again, they'll be about 2 years apart).

Can anyone else relate? Normal? Or a sign I'm not ready?
