Funeral Costs > Oxford Colorful Caskets
The photos on their site show really beautiful work, even fanciful. That might seem like a weird thing to say about a "death" product, but I know from my own experience with our son's death, the whole process of choosing his urn was awful.
This site offers options that seem so much more appropriate for children's caskets and urn holders. I particularly like that one with the very fanciful, fairy theme. Plus their site says, "design work free when child who has died is under 16 years...", so check out Oxfordcoffins.com for more information.
