How to get my sketches published?

Well, I've been sketching for years now, and people are always telling me they're really good, and my sisters mum said to me today I should go about and see if I could get them published in childrens books and things like that?

Does anyone know any websites or information for me of how I can go about doing this.

Thanks to everyone who replys :]

Good Luck!!! =)

I've just tried that Beautiful2u2 and nothing good has come up.

But thanks :]

Any other help?

Please.
