breastfeeding

It is official, my ds is now a year old. I am still nursing him four
times a day, and he seems to still really enjoy it/find comfort from
it. I am not sure how much longer I am going to nurse for. How do you
know when you are ready to wean? We are trying now for number 2 and
hoping to have success in the bedroom this time around. I feel like I
should be done with nursing before I get pregnant with our second.

Questions:
-How long did you nurse for?
-How did you know when you are ready to wean?
-Where you sad when you were all done?

Thank you
Kim
