HELP - registering in 2 days! Need a name!

I know this sounds awful but I still haven’t found the perfect name for my baby son. He is 5 weeks old on [name_f]Monday[/name_f] and we are registering him then too. I feel like describing how he is will help me find the perfect name for him.
He has lots of lovely dark brown hair, he’s nice and chunky, he weighed 10lbs 2oz, he has beautiful light eyes, he has two big sisters with nature related names. So looking for something different but that fits him well.
Thank you x

sorry, didn’t mean to post this here but have reposted a similar one in boys names!

I think you will want to repost this in the boy name forum.

My first thought with the sister names was [name_m]Jasper[/name_m], but I’m not sure it fits how you describe your son.

Some ideas…
