I seem to go two different routes with kid design - one is super stylized/Jonathan Adler funk-adelic. The items below fall in that category:
I have long been a fan of Charlie Harper illustrations. His illustrations would look great framed on a wall, or could be the jumping off point for your own custom mural.
Images below are from the Charlie Harper Studio, where you can buy lithographs and posters.






I would love the book (image from Amazon) with a retrospective of his work.
Disneyland's "It's a Small World" is a classic kids ride. We rode it incessantly as kids. The big ticking clock face has always reminded me of Jonathan Adler's Utopia collection. If Disney sold a clock with that face, I'd buy it for the next baby shower I attend. Image from here.

Orange and pink and monkeys. Need I say more?

While I’m not advocating the use of expensive Jonathan Adler pottery in a children’s room, I think the design motifs from his Menagerie and Utopia Collections make great inspiration for a custom wall mural. Wouldn’t an elephant in this style look amazing on a wall mural?



Like the whale wallpaper from my wallpaper posting!
The second route I seem to like for kids' design is uber-sophisticate.
This daybed from Oly Studio is a great piece that would transition from nursery through teens. It can serve as a spot for a tired mom or grandma in the early years, and be a great spot for a best friend to sleepover in or a good reading nook down the road.



Pottery Barn Kids has some sophisticated pieces for kids - like the chandeliers above.
