Ok...so how do i get some children

Ask your father.

EDIT: Edit; someone else covered it first!

You should probably talk to your parents about this...

Just kidding. All you have to do is get married. Children will eventually result, unless your spouse gets killed.  If you've really gone 1000 turns in a game without any kids showing up on the family tree screen, something is probably bugged in that game, and you should consider submitting it to support.

The simplest way is to recruit one of the champions wandering around the map. Once you recruit them, if they're of the appropriate gender, their action icons will have a wedding ring option. That lets you marry them. Kids follow later.

Apparently you have to marry someone to have a child. Just like real life! (oh wait..)  You can have up to four children and that is it, because, well, I don't really know.

That said, you can never remarry and never have bastard children. Why? Because... I don't know.

Seems it would open a lot of ground, much of it historical, if you had bastard children, annulments, etc.  Perhaps a factor of your wisdom in regards to bastard children? If you are wise, you know this could cause problems with your dynasty and perhaps have it tied to the wife. Obviously, if the queen is pregnant, she has a pretty solid idea of who the father is, unless she is on Maury "Who's the daddy" show. He has to take her word for it and that brought up many a device for preventing it and jokes for it.

There are several elements here that are not being explored yet. While controversial perhaps, they are part of the fabric of the genera.

Uless it's legal in your state, you must recruit a "female" champions to marry (not a male). . .

You lose half your kindom if she divorces you. . .

One factor to add to the above is 'status' (I don't recall offhand what the game calls it).  From my last game, and a friends, our Sovs started out with 0.1 (IIRC) status, and our prospective mates 1.0.  She wouldn't accept my offer, saying I wasn't "[I forget the term used]" enough.  I leveled as did she, same answer.  I removed her from the group, then I leveled and she didn't, then she accepted.  So if she (or he if your sov is female) won't accept try gaining a level (but not the prospective mate) then try again and it should work.

I personnaly i like the idea of wandering around killing stuff and having my wife get pregnant )

Wonder where the kids come from

Just click on a wandering female warrior and propose to here under actions!
Then you get married.. then wait awhile and down the road you will have a kid or two!
I had two kids in this one game of mine, but the son got killed in battle and so did my wife!

Now its only me and my daughter ):

Heh, I rather found it funny to have the pregnant wife leading my main army stack on a rampage through the country side. Then again that may be why my two kids were dumber than both parents...

Is there any way to boost the pregnancy rate? because I do see all the enemy factions having kids like mad while I had 1 in 300 turns.

Either my current game is bugged or that's (surprise!) not working currently.  My current game I'm playing as Markinn and I can verify he is both ugly as sin and quite fertile, with 1 daughter in the field and 2 more and a son waiting behind her.

Yeah i am always spammed with AI have children...

Couldn't we pay some woman to get children ?

This happened to me in game yesterday and I was like.. Hang on , I haven't even been home since we got married.

Janusk!!! 

Lol, thanks folks, i knew it was a simple fix, i had a feeling it might be adventurers of the opposite sex, though i could've swore i looked to see if there was an option, i'll have to try it. 

you need to marry as well as get the Tech Dynasty's   from diplo tree,

It's even funnier as a female sovereign leading the army, because it's *you* who gets pregnant and has the kid in the same turn you're fighting stuff.

It seems to me that the ugly trait should make it more difficult to get married, rather than to have children once you're married.

Last time I checked, rich and powerful ugly people don't seem to have much trouble reproducing in the real world. The game does, after all, have alcohol although paper bags can't be bought at the item shop.

An "infertile" trait should lower the chance of kids.

For those worried about husband and wife never seeing each other and still having kids, the censors cut the 0 mana spell 'Summon booty call' that is automatically cast at the end of turn summoning the wife to the channeller and returning her after.
