Q: I gave this puzzle to my 2 1/2 year old granddaughter for Easter. She had been doing 12 piece puzzles which "slide" together. This was a little more of a challenge since the pieces are "jigsaw", but she was able to do it. The edges are a little "rough", but our older ones may be smoother from many years of use.
A:
Positive
