Am I crazy!?

I just had my first child in May of 2020. I really want my children close together in age, and my boyfriend and I didn’t really plan to have more kids this soon, but I have baby FEVER you guys. I want to be pregnant again, I want to have more kids, and we do want them close in age. Would it be crazy to start trying again soon? Do any other mommas with kiddos close in age have any advice?
