Praying for a child

I have been praying that God blesses me with children. Now more fervently than ever. Everyday I pray for the blessing of children. I know it's in God's hands, and on his time, but I am relentless in my prayers. I think I know why he is waiting though. I believe God is waiting for my husband to ask for a child. My DH is devout, and a faithful follower of Jesus, but the idea of having children terrifies him. So my prayers have been amended to now ask for a child, but also to touch DH's heart and put the desire for children there. While I am constantly sad that I don't have children yet, speaking with Jesus comforts me. I understand he has plans for my marriage, and I just don't know what they are. Is anyone in this battle or similar?
