Let’s brainstorm more ideas.

I don’t have any more toys in mind, but there are probably a ton of ideas!  Maybe you could read some book about making building toys for toddlers and see what you can come up with.  Or you could create a web page and call it “Building Toys for Toddlers”, so other parents can get ideas from your post.

What are some good toys for kids who like building blocks?
user
A few ideas:

-Lego is often great for that

-Inexpensive Duplo can be fun too

-Lets brainstorm a few other ideas:
 
-If you like putting things together, puzzles might be fun

-For blocks themselves, you could try the toy blocks in the shape of the Chinese characters for “building” and “block”

I would I want toys in the shape of Chinese characters?

It sounds like you’re skeptical.  I agree it’s an unusual toy choice, but if the kid is a talented artist and particularly interested in drawing and writing characters, I think they could appreciate this.  In other words, if you think your child is creative and innovative enough to be a good Lego builder, you might want to try something a little bit different.  The blocks are actually very durable, and they’re essentially a wonderful canvas for drawing, creating, and writing.
