The Tyler I. identity

We named Tyler knowing his name was becoming a popular name and my plan was to give him a nickname. It never happened. When I text people I sometimes refer to him as Ty but I never call him that in person. Others have tried calling him TJ, Lil T, Tman, and a few other atrocious nicknames. Nothing sounded right. Sure we call him funny nicknames like bubs, buddy, midget, little boy, cutie, and so on but none are appropriate for a school setting.

So because of this we are stuck with the "I'm Tyler I." identity. I was a Sarah A. my whoooooole life. I never had a nickname except for a few nasty ones I would rather forget about. Mike started calling me Lee and it's nice to be the only Lee I know. I hated roll call at school and answering to Sarah A. or when there was another Sarah A. because yes that happened, then I was referred to by my full name. I never got to be Sarah. If my parents had intended for my to be called Sarah A. I'm sure they would have mentioned it. 

I don't want my kid to be referred to as Tyler I. But what can I do? Really? Can I start a nickname now? And what would it be? Certainly not one of the horrible ones people tend to use for a Tyler. I've tried asking him if he wants to be referred to as Tyler James which we do call him occasionally, or something else at school but he says no. And now when he introduces himself to people outside of school he calls himself Tyler I.

I know that he wont always refer to himself as Tyler I. but he will forever be just one of many Tyler's. Sure its our fault because we knowingly named him a popular name. No I wouldn't change his name but I would like to be able to skip the first name and last initial faze. Mike was probably a Mike I. and he of course is so easy going that it wouldn't bother him but it bothered me when I was a kid. It may never bother Tyler but what if it does?  What will he do? One day just come up with a nickname for himself? And how long will that take to stick? Or am I supposed to start something now? Nothing cheesy or lame, just something simple yet different. Not a name he must always be referred by but a second name to use like I do. 

What kind of nickname could I give him if I choose to do so? Any suggestions?
