Husband is annoying me

He wants to have another child when our baby that’s due in 6 weeks is 1. I told him “That’s a big NOPE ghost rider.” His reason is that he wants children 1 year apart so they can play and grow up together. And I get it, I wish my parents hadn’t waited 8 years between me and my brother and then 12 years for my sister because now I am grown up and they are barely entering teenage years and I can’t see them grow up everyday. It sucks. HOWEVER. pregnancy is not my favorite part of life—it doesn’t treat me well enough to be pregnant back to back. I told him that I believe a good age gap, and give me time to mentally and physically get ready for another child is 3 years. He claims that is too long and it won’t work out well. I told him to shove it and go to bed that he can make those decisions when he is the one carrying babies. Needless to say, he is annoying and I want to punch him sometimes.
