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
What LEGO set should you get a 4-year-old boy?
Look for boxes marked 4+. They have larger starter pieces and short steps a child this age can follow with a little help. City, Friends, Disney, Minecraft and others all make 4+ sets, so pick a line the child already knows from a show, a game or the toy box.
Can a 4-year-old build LEGO alone?
Often with some help at first. The instructions are pictures only, so many children this age follow them with an adult nearby, then take the model apart and build it again on their own.
What does the age on a LEGO box mean?
It is LEGO's guide to how complex the build is. A child who builds a lot can manage a set marked a year above their age; a child new to LEGO does better at or just below it.
