Have the puzzle for my little over 2 year old daughter bought the puzzling exceedingly zealous. The pieces are made of wood, very easy to grip for small hands, but first a little "tight" when cutting the individual parts. What I personally do not find so great is that the puzzle ends also go together, being but set incorrectly. With puzzles from Ravensburger the example is not the case. My daughter could not initially differ and figured if the part fits into it, it is also true so ...
But now she has come to know the image in itself closer and know what goes where thereabouts. Currently she needs already very much support it, but I'm sure they will do it in a few weeks almost alone.
