Bought a few puzzles for my 18 mth old as he's really into them. He loves these puzzles so I also bought the vehicles set too. Really good that in comes in different levels of difficulty. The 4, 6 and 8 puzzles ares pretty easy and the 12 piece took him a while to master. Lovely vibrant pictures and good quality. I think they're good for 18 mth + (recommended 3 +).
