Or is it inevitable? I love this name, but [name]Tom[/name] is a nickname I just can’t stand.
I think that you can call your son [name]Thomas[/name] at home.
I think that you can introduce him as [name]Thomas[/name] & correct anyone who calls him [name]Tom[/name] or [name]Tommy[/name]…I’m sure several people will. Hopefully you have a good relationship with your family members and everyone will be all about calling him by [name]Thomas[/name], but if your family is like mine and lack boundaries & respect they could absolutely [name]LOVE[/name] ignoring your wishes! Hopefully that’s not the case for you!
I do think that once your son is in school you lose a lot of control in this arena. He also might grow to like [name]Tom[/name] over [name]Thomas[/name]. If you really detest the name [name]Tom[/name] and couldn’t bear to hear your teen son referring to himself as [name]Tom[/name] maybe you need to reconsider [name]Thomas[/name].
Personally I take a name off my list if I dislike the obvious nickname cause I am prone to shortening names.
Depends - if he decides he wants to be called [name]Tom[/name] then no - but it is avoidable - my brother was [name]Thomas[/name] till he was ten then he decided he liked [name]Tom[/name].
I know three [name]Thomas[/name]’ that just go by [name]Thomas[/name] and never get called [name]Tom[/name].
I think so. [name]How[/name] do you feel about the nn Tombo (prn tom-beau)? Sure, it sounds similar to the word tomboy but I think it’s super cute. I second [name]Tommy[/name], as well.
I know only one [name]Thomas[/name] that goes by [name]Tom[/name]! All the others I know or have heard of go strictly by [name]Thomas[/name]. [name]One[/name] little [name]Thomas[/name] is [name]Tommy[/name] or [name]Toma[/name] but never [name]Tom[/name].
If your son dislikes [name]Tom[/name], then yes.
I have a cousin [name]Thomas[/name], and while he usually goes by that, it does get shortened to “[name]Tom[/name]” sometimes. They called him T.J. as a young child though - so would you be open to that? I am not sure what your middle name choices are, but I like the initial nicknames, especially if it is a “J” in the middle.
Always call him [name]Thomas[/name] and others will too.
You might not be able to avoid his friends calling him [name]Tom[/name] when he gets to high school though. He also may prefer it himself when he is older, but you can always call him [name]Thomas[/name].
My mother had this problem with my brother. She named him [name]Daniel[/name] but she hates [name]Dan[/name] and [name]Danny[/name]. Everyone calls my brother [name]Daniel[/name] except a few of his high school buddies that sometimes call him [name]Dan[/name].
My brother had a classmate named [name]Thomas[/name] too and nobody called him [name]Tom[/name] 
I prefer the full name [name]Thomas[/name] too.
I had a boyfriend whose name was [name]Tom[/name]. His mother only called him [name]Thomas[/name], but it always felt kind of schoolmarmish to call him by his full name, which has a formal, English quality. Everyone used the nickname, whether or not he introduced himself as [name]Thomas[/name]. So in my experience, it’s unavoidable. But I love the nickname [name]Tom[/name]. It makes me think of this:
If you really can’t stand the nickname then you’re going to have to pass on it because it’s only avoidable if your son or your son’s friends decided they don’t like [name]Tom[/name], which is unpredictable. Sure you can call him [name]Thomas[/name] at home, but if at some point he asks to be called [name]Tom[/name], would you be willing to?
All the [name]Thomas[/name]'s I know go by [name]Tom[/name].
I only know two Thomases and one goes almost exclusively by tommy, the other [name]Thomas[/name]. No wait I did know a tom in high school. So quite a varied selection! I met the [name]Thomas[/name] the most recently through work, and I admit I fought the urge to call him tommy almost every day for the first few weeks. It felt stuffy to call him the full name, as much as I do like it. But once I used it for a little bit it wasn’t so bad and it became more handsome than old sounding.
Because of that, [name]Thomas[/name] has made it into my long list. But because I don’t like “tom” and an only lukewarm on “tommy” I don’t think I’ll move it up unless my opinion on the nicknames changes because they just feel too inevitable.
Unfortunately , I think there will always be someone who’s going to shorten the name to [name]Tom[/name] or even [name]Tommy[/name]. If it really bugs you, just tell the person “No, his name is [name]Thomas[/name]”. They should back off. However, your son himself might want to be called [name]Tom[/name] one day.
I love [name]Tom[/name] for a nickname! [name]Tom[/name] [name]Paris[/name] from Voyager was a lot of fun. 
But yeah, I think you can do with out the nn if you want.
I don’t think it’s unavoidable. It mostly depends on what he wants to be called.
My name is [name]Kathryn[/name] and I have always been called [name]Kathryn[/name], except for a short time in high school when I wanted to be called [name]Katy[/name]. My twin brother is [name]James[/name] and has never been called anything but [name]James[/name]. People rarely assume that I go by something other than my full name. Sometimes they’ll ask “do you go by [name]Kathryn[/name]?” If they do just up and call me [name]Kathy[/name], I politely correct them (or ignore it, depending on the situation.) My sister, on the other hand, is [name]Elizabeth[/name], and she was always called [name]Elizabeth[/name] until she was in junior high and then she started letting her friends call her [name]Liz[/name]. Now she only goes by [name]Liz[/name].
If you love the name [name]Thomas[/name], I think you should use it. If you call your child [name]Thomas[/name] and he likes to be called [name]Thomas[/name], everyone will call him that. He may choose to go by [name]Tom[/name] at some point, but honestly even if you give him a name that doesn’t have any nicknames he could still develop a nickname for himself along the way.
What I would point out is that as a young man he may choose to be [name]Tom[/name] all by himself.
Personally I think [name]Tom[/name] is a strong masculine name and there are by far worse options out there.
I know two [name]Thomas[/name]'s both of which are in there teens. [name]One[/name] is only ever called [name]Thomas[/name] (that I’ve ever heard) and the other gets called [name]Tom[/name] by his older sister, but goes by [name]Thomas[/name] to everyone else.
As long as the [name]Thomas[/name] in question wanted to go be only [name]Thomas[/name], and not [name]Tom[/name] then it would be possible but there is no way to predict if he would prefer to go by a nickname.
