Lego Duplos are a wonderful toy for toddlers. Through planning, building, and pretend play, Duplos help toddlers develop important developmental skills—while having fun.
Open-ended building sets like the Lego Duplo line can open up a whole new world of inspiration for toddlers. Legos teach many skills that young children need to master, such as spatial reasoning and fine motor skills.
Plus, all Lego toys are made with ABS plastic, which is a non-toxic, stable plastic, safe for children. My kids love Legos and I love that they provide lots of entertainment and focused play.
Lego Duplo sets are specifically designed for babies and toddlers. The pieces are bigger than regular-sized Legos, so they won’t pose a choking hazard. And the larger brick size it makes them more accessible for tiny hands to put together.
Since Lego first launched the Duplo line, they have added a number of amazing sets. There are so many fun Duplo sets available today! You can find a lot of options on Amazon as well as on the Lego site.
Here are my favorite Duplo sets for babies and toddlers. Legos make wonderful gifts, too. In fact, Legos are my go-to gifts for kids of all ages.

This 36-piece set is age-appropriate for both toddlers and babies. It comes with a truck and a block for every letter of the alphabet. A boy, girl, and polar bear are included too, which I’m sure any toddler would get a kick out of.
This is a great set to help your little one learn to recognize letters, sing the ABCs, and enjoy the imaginative play together.
The blocks in this set are extra-large, so even the most inexperienced hands should be able to put them together. The set is recommended for children 18 months old and older.
This number train is very similar to the alphabet truck set. However, this steam train features numbers instead of letters, helping your little one recognize their numbers early on. (Because of this, the set comes with fewer Duplo blocks – 23 bricks in total.)
Two kids and a cat are included with this set as well, which gives your toddler something to play with on the number cargo train. This set is recommended for ages 18 months to 3 years.
So much of what makes Lego a great toy brand is discovery and creativity. This 80-piece set is perfect for just that.
Your little builder can be free to explore, create, and build whatever their heart desires! It’s one of the most open-ended toy sets on this list.
This set is recommended for toddlers 18 months and up, though it’s probably best for children a little older than that. It also includes instructions of 15 different models if your child likes to follow building instructions.
This set is very similar to the Classic Heart Box, but it comes with number blocks, flowers, a roof, window, and bread. This set also includes two people and a vehicle. This Duplo set is perfect for open-ended, imaginative play.
In total, this set comes with 65 Lego pieces, plenty for your little one to explore! There’s also a Deluxe Brick Set with 85 Lego Duplo pieces, if you’d prefer to have a larger set.
What child doesn’t love animals? This set includes 34 different pieces that turn into four different buildable animal figures: an elephant, crocodile, lion, and giraffe. You can also build a bird out of the blocks. All the animal figures are on wheels and can be hooked up to form a train.

The set comes with instructions to make a few specific models, but as always with Legos, kids can create whatever they dream up.
This is a pretty unique Lego set because the pieces make up animal block puzzles. Each puzzle has three pieces, though your toddler can mix and match to their heart’s content as well.
I recommend this set for very young children or those that love puzzles, and it’s an excellent introduction to the mechanics of Lego.
There are 15 pieces in all, which all have some part of an animal printed on them. It’s also a great tool to teach your little one to sort by color.

This is a basic set that only comes with six pieces, making this set perfect for a younger toddler—even as young as 13-14 months. Adorably, the pieces create a little ladybug car.
This car is best for younger kids because it gives them direction and the satisfaction of building a complete object without being too complex. It introduces them to the mechanics of Lego and how to put the pieces together without any frustration.

With 21-pieces, this small set includes a firetruck, tree, firefighter, boy, and cat. Even with very little building required, toddlers love to play with the scene.
It’s also an opportunity to encourage younger toddlers to learn new noises and words. Children who are learning to talk will love making firetruck and kitty noises.
For children who need a gentle introduction to open-ended toys, this 65-piece set is a good choice. Your child will love piecing together the house and car.
It also comes with a house and dog for more imaginative play. I like that the set has enough pieces for your toddler to make other buildings and towers as well.

Lego Duplos Are Great for Toddlers
Lego Duplo sets are a great way to introduce your toddler to Legos.
I love that they come as sets with themes to make it easy and fun for young children to build, imagine, and play. The bright colors spark the imagination and have a fun, childhood feel.
Legos are great for helping toddlers build their fine motor skills and my kids have absolutely loved them. I get most of my Legos from Amazon but also have started shopping from the Lego store for more options.
Are you a Disney family? You can even find Duplo sets featuring some of your toddler’s favorite characters such as Mickey and Minnie Mouse, The Little Mermaid, the cast of Frozen, and Woody and Buzz from Toy Story.
FAQs About Lego Duplos
What age is suitable for Duplos?
All Duplos will have an age recommendation posted on the box, and it’s best to follow the manufacturer’s age recommendations.
Pay particular attention to the age range listed on the box because some Duplos are recommended for toddlers as young as 18 months while other sets are recommended for ages 3 and up. Those sets that are for ages 3 and up typically have smaller pieces that are choking hazards and are therefore NOT suitable for younger toddlers.
Can a 1-year-old safely play with Duplos?
A 12-month-old is probably too young to play with Duplos, but around 18 months old, your little one might be more interested in playing with building bricks. As with all toys, your toddler should be supervised when using Duplos.
What’s the difference between Lego and Duplo?
Duplos are basically larger Legos, made for toddlers and younger children. They feature larger bricks that little hands can more easily stack and assemble. The larger size also ensures they are not choking hazards. Some of the Duplo sets for younger toddlers also feature smooth corners on the bricks so they don’t hurt your child if he were to put them in his mouth.
Classic legos are much smaller and require more precision and dexterity to use and play with. They are designed for older children who do not put toys in their mouths—typically ages 4 and up.
Are Duplos and Legos compatible?
Duplo sets are not compatible with classic Lego bricks, but they can be used together. So if you start with Duplos and build a collection, your child can still use them alongside their Lego sets when they transition to Legos. But the two will never fit together.
What kind of plastic are Lego and Duplo bricks made of?
Legos are primarily made of ABS plastic, which is considered to be a safe and stable plastic. It’s commonly used in food containers as well. The plastic is extremely durable and stable making it unlikely that it will breakdown even in the heat.
This is a perfectly safe plastic to be in your child’s toys. That said, it’s always smart to remind your kiddos not to chew on their toys.
What skills do Duplos help teach?
Your toddler will be working on a bunch of different skill sets when playing with Duplos. By stacking and building, your child will work on fine motor skills as well as hand-eye coordination.
As your child creates with Duplos, they will access problem-solving skills, planning, organization as well as learn how to balance bricks. You’ll see your child enter a big world of imagination while role-playing with figurines and a variety of settings.
Lego Duplos are really amazing toy sets that will continue to invite your child to enjoy learning through play over and over again!
