Boy or girl name?

So I am having a boy and my SO and I are trying to figure out names for him. One name he likes a lot is Tate, but if we would ever have a girl some day I like the tame Tatum/Taytum. I thought that Tatum was a girls name but I have heard of 2-3 boys with this name? What are your opinions.
Is Tatum a girls or a boys name?
And am I worng for not wanting to name my son Tate if I really like Tatum for a girl?
Also, would you spell it Tatum or Taytum??

I wouldn't name my son Tate if I wanted to name my daughter Tatum.

Tatum is both a boy's and girl's name.

And I would spell it Tatum.

i had never heard it b4 untill the other day talking to a momma on here and her little girls name is tatum.  

I don't like Tatum for a girl, but I like Tate for a boy.

Actually, I think Tatum might just be one of those names that grows on you.

I wouldn't use Tate for a boy if you really like Tatum for a girl.

BOY. It derives from a surname, which makes it, by default, masculine. Besides...all I hear is Tater and then I think of Tater tots and I get hungry.

When I look it up it says its for girls....maybe I'm just not looking hard enough

Quoting Amanda51:“ When I look it up it says its for girls....maybe I'm just not looking hard enough”

Oh, I'm sure you will find it listed for girls. What people don't understand is that people that run these websites, 9 times out of 10, have no clue what they are talking about. You can post whatever you want on the internet, true or untrue. 99% of baby name websites are complete and utter crap when it comes to the actual origins of names and the such. A good way to know if a site is reliable is if A) it cites it sources and B) doesn't include "modern English" names on their lists, thats a big tip off right there.
