When I was ready to have our second, I spent alot of time in prayer. At first, he wasn't interested because he has a son from a previous marriage. We had talked that I had always wanted two children, but he saw the money sign. We talked, but I tried not to push, but to explain my feelings. He became more excited about the thought of another baby, too. If this is God's will, he will, in his time, open the door to talk with your husband.
I breastfed both my girls. I wouldn't do bottles, unless I physically couldn't produce the milk. Be prepared that this will take time away from your other kids, husband, and yourself. My first wouldn't take a bottle even when I pumped, so I couldn't ever leave her for more than a couple hours at a time. On the other side, I loved the closeness and the bond that is just between you and the baby.
Prayerfully, T.
