Going by middle name instead??

I have a one and a half year old son named Jayden. I have some regret with his name just bc it’s everywhere 😒 i LOVE his middle name, which is Amari and I’ve considered calling him Amari instead. A lot of times when i call him i do say Jayden Amari, and a few times I’ve said just Amari to see if he caught on and he did. Do you think it’s too late to switch it up and do that?? Or should i just stick it out and keep calling him Jayden.
