Nickname help!

Pretty sure we are gonna name the baby Richter (Rick-ter) but we don’t like the nickname Rick. We would rather call him the full name than say that lol. Just makes us think walking dead.

What other nicknames could we use? My moms already just calling him by the middle name haha so I don’t think she likes rick either.

Someone suggested Richie but I’m still trying to think of options.

And yes I know it’s not a common name lol my husband picked it out and he’s really in love with it

Edit: I know about the Richter scale lol but he took the name from castlevania pretty sure
