I'm an equal opportunity nicknamer.

#sonOne (age 42) was still called "Diaper Butt" long after he outgrew that nickname, and still gets it on his birthday.

#Daddy_A (age 30) still gets called by his (now embarrassing) childhood nickname that he outgrew around age 10-12.

Now, #Little_Boy_A (age 6) retains his old nick.
