Hi S.,
I totally sympathize with you! My husband is the oldest of six children and he has definite reservations about having another baby. I have talked about it since our son was 2 months old! (He will be 2 in April.)
At first when I talked about it, my husband was like yours, he would get an attitude or he "didn't want to hear of it."
Then, as our son got older, I realized how much work it is raising kids. Infants are hard, but not as demanding as toddlers. So I started opening up with my husband. I would tell him that I wanted to wait to have kids, the reasons why, the pros, the cons....I made it more like it was "our" decision, vs. me just dying to have another one. I also started talking openly with our friends about it. I'd say "well, Jared isn't ready for another baby" or "My wish is to have another baby, but Jared's not sure." At least this way, I respected his opinion, but I wasn't going to "hide" much less comply with him. And I didn't want to sound degrading, but I had to bring it out in the open. The more I did that, the more he could see that I was listening to him and his reasons, but I still had my heart set on another one. I also told him the emotional side of how I felt. (And still feel.) That having a baby was so much a part of me, I couldn't possibly turn the feeling off or not listen to it. And if that doesn't work....just tell his mom he doesn't want anymore! ha ha....No, I'm kidding, I'm not trying to make this out like it's a joke or my intention is to trick my husband. I did, however, mention it to his mom that he didn't want anymore kids and she really gave it to him. Plus, his brother has a child close in age to ours and they are ready for another one.
So I guess, S., just being patient and understanding, but expecting the same from him in return. I know it's so hard, but I guess that's what marriage is. Give and take. He may see how serious you are about your decision.
My MIL said that her husband did want ANY kids and she ended up with six! Miracles do happen! She said she never even talked to her husband about it, she would just start praying....
Our son will be two in April and I keep telling my husband I want to try in July. He won't really say one way or the other how he feels, but I do know he is listening. Just the other day we were at the dentist and our hygentist said to me "Your husband says you might be trying for another baby this summer?" They listen, even when we don't think they are!
Best of luck! I'll let you know how this July is!
