My daughter 2 years 4 months is a real fan of the Little Mole. Because of the good reviews so I ordered this puzzle. She has an interest in the puzzle, the subject likes it. We puzzle it together, but she still manages. The parts are tacky feel, and not too small. I think from 2 or 2.5 years old can be such a 15-parts puzzle frame perfectly willing. Oh, and particularly to the puzzle, I like that the parts look like puzzle pieces, as I unfortunately had already ascertained, that's when this type puzzles not always so. There are also puzzles that consist only of curved parts.
