What are your thoughts on just using the name [name]Katie[/name]? I love the name [name]Katherine[/name], and would use it, but I have a cousin named [name]Katherine[/name], and I would always just call my daughter [name]Katie[/name], so is there a point to using a full name?
On one hand, I get where you are coming from. If you’re never going to use a name…why bother even use it?
However, I also like having the option of a full first name. I think it gives the kid more options. If they decided when they are older that [name]Katie[/name] isn’t very professional sounding they can choose to go by [name]Katherine[/name]. Or possibly even something like [name]Kathy[/name].
I think [name]Katie[/name] is one of the “short names” that would work on its own. It does admittedly have a cutesy, little girl image to it…but I know a few different [name]Katie[/name]'s from different walks of life, and the older ones I know I don’t think had a hard time gettting hired or getting passed up by someone with a more formal name.
But yeah, I do think it is pretty pointless to use some longer name if you plan to just call her [name]Katie[/name] all the time.
My first cousin is just [name]Katie[/name], and it’s never been an issue to have a common “nickname” as her full name. If you like it, I say go for it!
I’m a [name]Katherine[/name] who goes by [name]Kate[/name] and who used to go by [name]Katie[/name] as a kid. I almost never use [name]Katherine[/name], but i love having the option if I wish. It feels like my ‘official’ side, which I can use or drop as I like. I also switched from [name]Katie[/name] to kate when going to college, because [name]Katie[/name] felt childish and young. Plus, with a longer name I love that i could be a kat, [name]Kate[/name], [name]Katie[/name] ([name]Katy[/name]), [name]Kathy[/name], [name]Rynn[/name] or maybe even erin though it’d be a stretch. I appreciate that sort of flexibility, even though [name]Katie[/name] and kate are still my all time favorites.
I know several girls/women named just [name]Katie[/name], and it works just fine for them.
I do love [name]Katie[/name] on its own but would probably use [name]Kate[/name] on a birth certificate. It just sounds more formal to me.
I wouldn’t use it but other people have. I think it feels too “cute.” It is lovely as a NN but its all NN to me. And I suspect that while [name]Katherine[/name] is timeless, the nicknames cycle in and out - [name]Katie[/name] in 30 years will feel as middle-aged as [name]Kathy[/name] does now.
If [name]Katherine[/name] felt too “taken” I would probably explore [name]Kathleen[/name]/[name]Katja[/name]/[name]Katarina[/name]/[name]Caitlin[/name] etc. I don’t think I would need it to be a K spelling to be called [name]Katie[/name] either - plenty of Catherines/Caitlins go by [name]Kate[/name].
I went to high school with a girl who was just [name]Katie[/name] so it seems perfectly normal to me.
I like it and think it can work just fine.
[name]Katie[/name] is too cutesy. I prefer [name]Katarina[/name] / [name]Katerina[/name] as an alternative to [name]Katherine[/name].
My best friend through middle/high school was just [name]Katie[/name], so to me it seems doable.
This is how I personally feel (as in, for my kids), but this subject in general is frequently discussed on here and there are always lots of responders who say “If you’re always going to call her that, why not just use that as her name?” So it’s definitely a perfectly acceptable way to go.
That said, I know a (just) [name]Katie[/name] and she hates how people ask her all the time what her full name is and gets very annoyed by how surprised people are that her name is just [name]Katie[/name]. I’m not sure if she wishes she had a longer name, but she definitely wishes people were more accepting of it. She’s in her 30s though; your daughter will be growing up with Madysson, McKinzee, [name]Jayden[/name], and the like – [name]Katie[/name] will be a breath of fresh air. 
I [name]LOVE[/name] [name]JUST[/name] [name]KATIE[/name]! It’s the name I used to give myself when I was little and played house with my sisters! I always wanted to be a [name]Katie[/name], and I would love to see a just-[name]Katie[/name]. It would be on my list for a daughter if I didn’t have so many other darn names that I liked. It has a nice '80s and '90s ring to it, and takes me back to the days of Cabbage Patch Dolls and Beanie Babies. Very nostalgic. If [name]Jamie[/name] and [name]Kelly[/name] can be full names, [name]Katie[/name] can too.
…I mentioned above that [name]Katie[/name] isn’t on my list, but that’s not entirely true. I do have the double-barrel name “[name]Katie[/name]-[name]Jane[/name]” on my list that you may like. [name]Feel[/name] free to steal it if you like it. I likely won’t use it anyway, only because we have SOO many girl’s names. [name]Katie[/name] would be cute with just the middle name [name]Jane[/name] too, rather than making it a double-barrel first.
I think [name]Katie[/name] on it’s own is perfectly fine! However, I do understand the appeal of having [name]Katherine[/name]/[name]Katerina[/name]/etc as a longer option or [name]Kate[/name] as a more formal one. My best friend is just [name]Katy[/name] and it’s never held her back though!
I am also a [name]Katherine[/name] that has gone by [name]Katie[/name] my entire life. I also know a number of Katies that [name]Katie[/name] is their given name. I think it works either way, however I like having the formal [name]Katherine[/name]. I feel it does give you more options, and is less nicknamey that just [name]Katie[/name]. I have gone between [name]Katie[/name] and [name]Kate[/name] for much of my life, so I feel that both work for kids as well as adults. The one complaint I hear from legal name [name]Katie[/name]'s is that they are always asked “What is it short for?” or “You’re just [name]Katie[/name]?”
Plus I always knew when I was really in trouble because that was when my mom would pull out [name]Katherine[/name]. 
I can see [name]Kate[/name] working on its own. But [name]Katie[/name] seems too childish.
It is on the cutesy side, but sometimes having a longer name just for the sake of having it is counterproductive if you prefer the shorter variation.
My mom is named [name]Kathy[/name]. She has always enjoyed the fact that her mother didn’t name her [name]Katherine[/name] or [name]Kathleen[/name] and just [name]Kathy[/name].
Although, I can see the benefits of using a longer name to give a child options.
I’m in total agreement about using the name you will call her by. It’s just that [name]Katie[/name] is a little bit cute. I’m going against what I almost always suggest here, but I feel sure I’d use [name]Kate[/name] on the birth certificat and call her [name]Katie[/name]. Then she has a more grownup option for later.
I’m the type of person that would go with a longer formal name and use a nickname for everyday use. I find [name]Katie[/name] too nicknamey and cutesy for a full name. I like the idea of flexibility in the name, and that the child can choose what name to go by. If she were named [name]Katherine[/name] or [name]Katerina[/name] or [name]Catalina[/name] or something along those lines, she can pick a nickname, especially if she doesn’t like [name]Katie[/name].
My mother was “just [name]Cathy[/name]” and she frequently spoke about how she wished that she had a non-nickname name.
