Nickname ideas for Charles

We named our youngest Charles thinking we would be likely end up calling him by a nickname. He's approaching his first birthday and we still are stuck on what to call him. Charles seems a bit much for a baby/toddler but none of the common nicknames for Charles seem right. My husband doesn't like Charlie. I am not a fan of Chaz. Chuck and Chip feel just ok. Looking for other ideas and open to non-traditional or less common nicknames for a Charles.
