Well....When I was ready to try for our first, I just told him I wanted a baby. He didn't think I could get pregnant again so he didn't really say yes or no, he just assumed it wouldn't happen.....
Let's just say when I was 8 DPO and had two VERY bright lines on multiple tests, he was a bit shocked! Hah.
I just told him I wanted another baby. I have been saying it since DD was 6 months old. He finally didn't shoot me down so I had to IUD taken out and he got a lot more sex out of the deal.
DH asked what I wanted for mother's day. I told him Zumba for Wii or another baby. He woke me up on mother's day and said well, here is your Zumba you will need it to get back into shape after we have another baby. A year and a half later the babe should be here any day.
After DD, it took a long time before another baby was discussed due to me being traumatized by her birth. It wasn't until spring 2010 that I brought it up and he was all for it. We wanted to wait until after DD's surgery and recovery to try, so we started TTC December 2010.
With our 2nd we had just moved into our new house in March, I was pregnant in July! We just knew we wanted another Baby. With our 3rd, I waited to lose a bunch of weight, so once that was achieved, we got pregnant Our third little girl is 7 weeks old. No more babies though, this is it.
