Our boy's name should be similar to the baby boy's name and the brother's name... dilemma!

Hi everyone, I’m facing a dilemma. We’re finally pregnant with our second child! We don’t know if it’s a boy or a girl yet. Our first is a girl, and we’d already come up with a boy’s name for her that we still think is the most beautiful. The problem is that my brother recently had a son with a similar name—not exactly the same, but pronounced the same way. Like, say, Tim and Pim. My husband doesn’t have a problem with it, but I keep wondering if it’s really okay. There are so many other names out there, but none that feel like they could ‘replace’ the first one, in my opinion. I’d love to hear your thoughts on this.
