Baby girl name!

Caitlin • 1st born May 2017, 2nd born May 2020, 3rd due May 2024 💗

I’ve posted polls asking for opinions and of course it turned out 50/50. We originally chose Brielle but now I’m worried it’s common and that she will be nicknamed Bri which is obviously common and now I am thinking I kinda like Brynn. Thoughts? Opinions? Husband prefers Brielle but also thinks Brynn is cute. I think he mostly doesn’t understand why I’m freaking out about it changing my mind but it’s just a huge decision 🥺 please help
