“Always end the name of your child with a vowel, so that when you yell the name will carry.”
― Bill Cosby
Make them names that roll off your tongue. You will inevitably try to call them in order, and mix them up. My last three sisters all had a “K” sound in their names, which made things a bit confusing.
It’s true about vowels. Try it with “John”, “Chad”, or “Alexis”.
