Julian - he's getting teased already by his own cousins

I would tell them quite abruptly, that it just isn't on.
It isn't nice, don't do it.

They are your nephews - go for it!

FWIW - I love the name Juilian!

I think you do need to tell your nephews to stop picking on him.

I have a friend called Julian. I've known him since we were teenagers and no one has ever called him Julie, not even at school. Sometimes we call him Jules.

My youngest is Julian and I've been lucky no one has teased him, but he has 4 older brothers.

I agree with Tellytubby, there are you nephews either speak to them and say it's not on, or speak with their parents and get them to explain that names can hurt even if they think it's fun at the time.

I went through school with 2 Julians, they never got teased.

My DH is a Julian and I tease him I often call him Julie or Julio or lots of other names to be honest and not all of them good ones
He gets called Julz alot by his mates but even he said that the alot of the Asian guys at his work all call him Julie (sounds like Juri)

I would tell the nephews straight out that its not on. I would expect my siblings to tell my kids off if they deserved it and especially if they are bringing out your "mother lion" I would definately let them have it.
