So I download and installed what I thought were playable elf child mods and yet all I get when I start a new game is a playable Drow child and a playable Orc child. Why aren't any of the other races showing?

Here is my load order:

(0) Skyrim.esm
(1) HearthFires.esm
(2) RaceCompatibility.esm
(3) Update.esm
(4) Xvision Children.esm
(5) Vedaa_Race_TESV.esp

I tried http://www.nexusmods.com/skyrim/mods/52253/?tab=2&navtag=http%3A%2F%2Fwww.nexusmods.com%2Fskyrim%2Fajax%2Fmodfiles%2F%3Fid%3D52253&pUp=1 and http://www.nexusmods.com/skyrim/mods/38712/?tab=2&navtag=http%3A%2F%2Fwww.nexusmods.com%2Fskyrim%2Fajax%2Fmodfiles%2F%3Fid%3D38712&pUp=1 and I get a crash to desktop. I'm thinking I may need to get the expansions for Skyrim. http://i.imgur.com/OPg7alV.jpg is what my Wrye Bash looks like.

As far as I can tell, you don't actually have any *playable* elf children mods. You have that hideous Xvision addon which just adds some around the world. Playable Children Plus adds (extremely buggily and without much in the way of compatible clothing or any equipment) humans and Dremora.

So, you should be able to see those, but you apparently can't. If you are hoping to see a playable Dark Elf, you will not. Does skin tone adjusting the Drow not get anywhere close?

Skykids has "Playable, functional, child versions of all vanilla races with both genders(including beast races!)". Google for it as it's on a site which it isn't allowed to link to. Note that I haven't tried it myself so I can't say anything about the quality of it etc.

Yeah, Lovers Lab is a great site. Unfortunately for me, Skykids requires Dawnguard. But thanks for pointing me in the right direction, Arkngt. Perhaps after next paycheck I'll go pick up the Legendary version at the store.

Your playable children mod that's highlighted blue in your Bash pic also says it needs Dawnguard and Dragonborn. Surprised that would even run at all considering.
