Really want a baby

I have had two miscarriages, one in August 2016 before I had my little girl and one in October this year just before my little girls birthday. My partner and I haven’t really spoke about it the second time as it felt a lot worse because we had a scan and saw a heartbeat etc. The only thing he has said is that he doesn’t want to try for another. We were both really sure after my little girl we would have another but he’s scared in case we miscarry again. I admit at first I felt the same but now I feel like I really want to have another baby. I don’t know how to start a discussion with him about it because he will just dismiss it. Anyone got any advice ?
