We ordered this jigsaw for our granddaughter age 2.
Unfortunately two of the pieces didn't fit together. We received a replacement, but unfortunately this didn't fit together either - different pieces.
Also, as a final attempt, we were unable to match the two jigsaws together.
If they had fitted then it would have been suitable for a 2-4 year old.
Also we were unable to contact 'Melissa & Doug' direct - no response on emails?
