    LEGO Duplo counting train set

    Ages 1.5+

    A Duplo train building set built around numbers, with bricks to snap onto the cars, rearrange and count while rolling it across the floor.

    23 pieces · set 10954

    Why we like it

    Numbers ride along on the cars of this Duplo train, giving all that out-loud stair counting a new place to go.

    Call out a number, like three, and the hunt is on to find that brick and press it onto the train. Lined up in order, the cars make counting something to push from one room to the next.

    Pick 2 of 20

    LEGO Duplo building brick set

    Ages 1.5+

    A Duplo building set of bricks to stack, press together and pull apart into towers, houses, roads or whatever takes shape.

    65 pieces · set 10913

    Why we like it

    Towers stop growing when the bricks run out, and a preschooler building tall runs out fast.

    The Duplo Brick Box adds a fresh supply that works on its own or mixed in with the Duplo already at home. With more to go around, one lonely stack can grow into a whole street of houses.

    LEGO Duplo vehicle brick building set

    Ages 1.5+

    A Duplo building set of bricks for snapping together vehicles, then pulling them apart and rebuilding the pieces into fresh designs.

    42 pieces · set 10474

    Why we like it

    To a three-year-old, a crash is half the fun, and anything with wheels heads straight for the nearest wall.

    With these Duplo Creative Vehicles, a smashed car is no loss, since the same bricks rebuild into something new to push.

    LEGO Duplo castle building game

    Ages 3+

    A Duplo brick set that players assemble into a castle, then play together as a game around a table.

    47 pieces · set 10450

    Why we like it

    Family game night has room for the youngest player when the game itself is made of Duplo bricks.

    In Hopsy's Castle Game, everyone builds the castle first, then plays the game around the table. Afterward, the castle can stay standing for a three-year-old's own pretend play.

    Pick 5 of 20

    LEGO Duplo penguin and lion set

    Ages 2+

    A Duplo building set with penguin and lion families to put together and use for pretend play about life in the wild.

    10 pieces · Fits a stocking · set 10442

    Why we like it

    Lions and penguins make an odd pair, and that is the appeal for a toddler torn between roaring at big cats and waddling like a penguin.

    Both arrive as Duplo animal families, ready to put together, feed and march around. At snack time, the penguins can line up beside the plate while the lions wait their turn.

    Pick 6 of 20

    LEGO Duplo Peppa Pig market playset

    Ages 2+

    A Peppa Pig building set from the Duplo line that snaps together into a tractor and market for pretend shopping and farm stories.

    18 pieces · set 10468

    Why we like it

    Playing store in Peppa Pig voices goes further with a market stand to run and a tractor to haul in the goods, both built from Duplo bricks.

    The tractor pulls up with the delivery, the stand opens, and anyone who wanders past becomes a customer. The market stays open as long as there is someone left to sell to.

    LEGO Duplo Mickey Mouse clubhouse set

    Ages 2+

    A Duplo brick set from the Mickey & Friends theme for putting up a clubhouse, then playing out stories with Minnie and Pluto.

    87 pieces · set 10465

    Why we like it

    Mickey's own clubhouse is the build here, and Minnie and Pluto arrive as his first guests.

    Once the house is up, the builder decides who knocks first and whether Pluto gets the spot by the door.

    LEGO Duplo Frozen building brick set

    Ages 2+

    Duplo brick set from Disney Frozen with Elsa and Olaf, for snapping together simple scenes and buildings, then pulling them apart to build something new.

    37 pieces · set 10462

    Why we like it

    Elsa and Olaf are both in the set, so the very first build has a job: a tall ice palace for one, a snowy hideout for the other.

    Compared with a single Frozen doll, this gives a young builder two characters and a heap of bricks to rearrange their little world as often as they like.

    LEGO Duplo F1 race car set

    A Duplo F1 building set with race cars and driver figures to put together, roll across the floor and line up for pretend races.

    70 pieces · set 10445

    Why we like it

    While motor racing plays on the family TV, a three-year-old who cheers every overtake can build a grid of her own.

    Those 70 Duplo pieces turn the sport she watches into a team she snaps together and steers herself. Each driver figure hops into a fresh car whenever the lead changes on TV.

    A Duplo farm building set about caring for bees and beehives, with bricks to put together, rearrange and use in pretend play.

    22 pieces · set 10419

    Why we like it

    On a garden walk, a three-year-old who crouches beside every buzzing bee is ready for a Duplo set about caring for them.

    Its 22 pieces give that curiosity a hive of its own to stack up and tend. The finished hive gets a spot on the shelf, proudly shown to anyone who visits.

    Why we like it

    This LEGO Duplo family house gives a three-year-old's playing-house games a home of their own to build.

    Its 218 pieces come apart and snap back into a new layout whenever the pretend story changes. Mealtimes and bedtimes can then play out room by room, just like at home.

    116 pieces · set 10435

    Why we like it

    This Duplo palace hands Ariel's undersea world to a three-year-old Little Mermaid fan to build.

    Its 116 pieces make a build worth sharing with a grown-up, so the palace goes up over an afternoon. Once it stands, Ariel can host whatever undersea story the builder dreams up next.

    Ages 1+

    A box of 80 Duplo bricks to stack and snap into whatever the builder imagines.

    80 pieces · set 10909

    Why we like it

    The Duplo Heart Box holds plain bricks for a three-year-old who builds whatever comes to mind.

    Its 80 pieces leave room to make up a new build each day, with no story to follow. After breakfast, yesterday's tower can come apart and turn into a bridge.

    Why we like it

    This Duplo police motorcycle makes a small add-on for a preschooler with a Duplo town at home.

    160 pieces · set 10998

    Why we like it

    The LEGO Duplo 3in1 Magical Castle gives a Mickey & Friends fan a castle to build and rebuild.

    Its 160 Duplo pieces come apart and go back together as several different toys, so there is always a new build. After breakfast, Mickey and Minnie can move into whichever castle stands that morning.

    27 pieces · set 10938

    Why we like it

    This Jurassic World Dinosaur Nursery makes a dinosaur-loving preschooler the keeper, with Duplo bricks to build it all.

    Not sure where to start? Answer 4 quick questions

    Open these in the GiftExperts LEGO Finder

    What age is LEGO safe for kids?

    LEGO sets with small pieces carry a choking hazard warning and are not for children under 3. DUPLO is made for children from 18 months, and most LEGO sets start at 4+.

    Questions and answers

    DUPLO or LEGO for a 3-year-old?

    DUPLO for most 3-year-olds. DUPLO bricks are twice as long, high and wide as standard LEGO bricks and made for small hands, while most LEGO sets start at 4+. Some 4+ LEGO sets are made for the step up from DUPLO, with larger starter pieces. DUPLO bricks also click onto LEGO bricks, so nothing goes to waste later.

    What DUPLO set should you get a 3-year-old?

    Start from something the child already loves, such as animals, trains, cars or a character from a show. A set with a figure or two and a vehicle or a small scene gives them something to play with once it is built, which matters as much as the building at this age.

    Is there a Duplo set the whole family can play together?

    Yes. The Duplo castle game is built from Duplo bricks first, then played as a game, so the youngest player at game night has a seat at the table.
