The World of Eric Carle: Nesting Blocks by Kids Preferred


Ok, parents. These nesting blocks are the bomb. They are on my list of essentials, even though they are a toy—because babies need stimulation and play in order to learn! But you already knew that. What you may not already know is that these blocks just may give you a cart-attack. They are THAT amazing.

You have probably heard of or already own some of Eric Carle’s top-selling children’s books. We have The Hungry Caterpillar box set, and we get LOTS of use out of it (but that’s a review for another day). These blocks feature Eric Carle’s signature illustration style and characters.


Eric Carle Stacking/Nesting Blocks are a set of 10 paperboard blocks that are open on one side. They can be nested together or stacked (like in the pic above). Each block represents a different animal, color, number, and group of letters. They are illustrated with all the characters from the author’s books so toddlers will recognize their favorite characters too. They are recommended for ages 6 months+.

PRICE: $17-20



my son nesting the blocks

We received these blocks as a Christmas gift for my son, Kai, when he was 9 months old. He’s now almost 11 months, and they are still a go-to for playtime. We usually keep them nested once he’s done playing, and the next time he encounters them, he loves pulling them apart. (His daddy taught him to take them apart at about 9.5 months.) But they do more than that—he also loves to put things inside the boxes, like a small ball or other toy. Kai can re-nest them if we help him pair a smaller box with one that’s a couple of sizes larger so it’s easier for him. He will sometimes put the small boxes inside large toys, like a bowl or his barn. And if we stack them for him, he loves trying to grab one of the boxes as well as knocking them down. We’ve used them to build a “city” and to create a valley for his train to drive through. We’ve created obstacles for other toys to encounter with them by creating stair-steps for his giraffe to climb up, or putting one of them on his stuffed animal’s foot like a shoe or on the head like a hat—he’ll usually smile and pull it off for them. Even though he’s a little young, we use the toys for repetition and teaching him colors, shapes, animals, and numbers.

Are you with me? Off the top of my head, I just listed TEN uses for this toy!

  1. pulling them apart
  2. putting things inside
  3. re-nesting them
  4. placing small boxes inside other toys
  5. knocking down a stack or taking one from the stack
  6. building a city
  7. creating a bridge or valley for vehicles to drive through
  8. stair-steps for other toys to climb
  9. creating shoes and hats for other toys
  10. teaching colors, numbers, etc.

That’s just what he can do with them right now. Eventually he’ll get the hang of stacking them himself, and he’ll probably take on the creative role with them as he gets older. Sometimes the simplest toys really are best! Playing with them was intuitive for him and I think the fact that they are simple makes them a creativity magnet.

They also come in a perfect-sized box with a handle for easy travel. We’ll be taking them with us on our vacation coming up in a month since they are so easy to take along and will help him stay entertained.

And I’ve heard that these blocks keep a toddler’s interest and we’ll get LOTS more use out of them, from months to years from now!


I bet you’re wondering one thing: Will they hold up to baby drool/biting?


On the left: the joys of teething! On the right: the damaged block holding up pretty well.

My short answer is yes. But here’s the longer answer…Kai went through a phase where he would only want to use these to bite. He’d grab one and start grating it with his lower teeth. On one of them, he started scraping away the coating in one small spot—luckily I was right there to make sure it didn’t come loose and end up in his mouth (see pic). We put the blocks away for about a week, and would occasionally test it out to see if that was still what he wanted to do with them. Every time he started scraping them with his teeth, we’d just put them away. After a week, he was done. It doesn’t even occur to him to try it any more, to the point where I almost forgot to mention it here. Drool wipes off easily.

They are paperboard, so they are susceptible to some damage. But I prefer that they are lightweight instead of plastic or wood because my baby can throw! My husband actually sat on one of the blocks one day, but to our amazement, the block was just dented (see pic). We still get a lot of use out of our one deformed block, and actually, it’s one that our son gravitates towards because it’s different.


★★★★★ 5/5

These blocks are just the perfect toy. They are educational, stimulating, and creativity-inspiring, and have provided countless hours of fun for my little boy. They are my first cart-attack MUST-HAVE product and my first review because if I had to pick only one toy that we’d get our son, this one would be it. My advice to those of you waiting to put these in your cart: stop it! 🙂 Toss it in and your baby will THANK you…you know, once they can actually speak.
