How to get people to use baby’s first and middle name?

So my husband got his choice for the first name and I got my top pick for baby’s middle name. My question is how do I get people to do that cute thing where a kid is called by their irst and middle name in an endearing way?

For example singer : Thomas Rhett goes by his first and middle his full name is Thomas Rhett Akins.

It’s not the end of the world but I feel like I keep calling him Tucker Rhett and everyone else just sticks to Tucker. I was hoping it’d just catch on but no luck yet…
