I think you just need to find the right time and be honest with your DH.
After DD2 was born both Dh and I were adamant that we were finished. We were happy with our little family. Then in the year after DD2 was born we went through some things that made me change my mind. I just knew we werent finished. Perhaps my saving grace was that I blurted it out to Dh as I realised that I wasnt finished, neither he or I were ready for the conversation. It took a lot of talking, a lot of understanding but we worked it out. Obviously we decided on a 3rd. :)
But you need to talk to each other. Come to a decision, it may mean that you need to talk a few times, but you need to.
