Husband wants more kids…. But I’m still pregnant 😂

So my husband has stated multiple times through my pregnancy he wants more kids. I usually laugh it off, or just tell him no I’m waiting a while after this one (baby #2). I’m due in a month now and I was planning on doing some sort of birth control, but now he’s saying he doesn’t want me to go on birth control. A lot of it has to do with the hormonal issues I was having before we decided to have this baby when I was on nexplanon, but still. I really don’t want to have another kid so soon after this baby is born, but I don’t know how to approach him seriously about the topic. Plus we haven’t even had this baby yet, and I don’t think he realizes how much of a toll it will take financially and emotionally/mentally. What would y’all do in my shoes?
