can you change yourself into a child

[Ariel Vuissent]

Sure. There are all kinds of things for child avatars out there. You'll want an appropriate shape, skin, and clothing, plus an AO, and perhaps some accessories. Age, style, etc, are up to you. Check out the marketplace for a start.

In  addition to the other answer/s;
you can also do that on your own. If you are up for experimenting a bit with it:

Make a new avatar-shape and play with the shape sliders and make yourself small, and try to adjust towards the generell looks and visual nature of a child.

Also try out your clothing items (if you have modify persmissions) and resize them to fit onto your new child size. (just make a copy of them first to keep one normal sized version of it) Same with Hair, Shoes etc.

I am allways for encouraging to try things on your own before buying. =)

But of course you can go also the more comfortable way and check out the market place as the other answer suggested. No shame in it, and they have great stuff for child avatars.
