Use the Nexus mod manager to place the files in the right folders.

This is a completely standalone set of meshes and textures to revamp all twenty-three boys in Skyrim and Hearthfires. For examples of how they look

please see the screenshots. Like others, I was brassed off talking to identikit boys.

The single male child head has been reworked somewhat to give some variation in facial features and to make the modifications fit on the new bodies.

To this end, if you adopt any of the boys and want to give them a new set of clothes and don't want obvious neck gaps, please select the YELLOW tunic for them,
though Francois and Sam can use any of the variants.

If you are already using one of the child altering mods, as long as this is loaded last, I think it should be compatible.

As many of you will be aware there is a bug in the game which greys facial features. The partial fix for this has been to load in twenty-three FaceGenTextures
and so, if you are asked whether you want to overwrite any of the files when this mod is loading, just say 'yes to all'.

You may be also aware of another bug in Hearthfires about wearing clothes. If you have given them a nice new tunic to wear including my yellow one, they will,
as like as not, the next time you play, have reverted to whatever they were wearing when you first met them. They will then change clothes randomly at every load.

It is also important to note that if you are in an area where there is already a boy, he won't change in front of you when you load. So duck into the nearest shop
or something and when you come out, there he'll be in all his finery, or not.

I learnt how to make this mod through dissecting the x-vision children mod and, though I decided not to go down that route, it was a good learning guide.

There is now a version of this mod which will load without the Dawnguard add-on, but it does still mean you need Hearthfire, but it is very cheap and you can spend
hours building a house. (Yawn.)
