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+.
Sets marked 9+ suit most children this age. Technic, NINJAGO, Star Wars, Harry Potter, Friends and Creator 3in1 all build at this level. For a child who already builds a lot, a larger set from a theme they follow makes a good main present.
Yes, most can build a set marked for their age alone. Large sets come in numbered bags and can take several sessions, so they can stop and pick up again where they left off.
It is LEGO's guide to how complex the build is. A child who builds a lot can manage a set marked a year or two above their age; a child new to LEGO does better at or just below it.
