If my husband do not want another child although we have one child only. How to convince my husband to try another child?

What is the reason? I was preggy recently, initially we didn't want it. We both agreed it was too soon. Since my son would be barely 2 when i deliver, and i dont think i can handle newborn + terrible twos. And i'm looking forward to head back to work. Financially its going to be very taxing as well. I discovered i was preggy at 6weeks. When i was 2 months + preggy, I almost had a change of mind though, my hub also said he's open to it. But unfortunately i had a miscarriage. I guess just take sometime and really discuss the reasons. And when you're both ready, #2 will come!
