I bought this puzzle of my 13 months old daughter. At first she just dumped the parts. Shortly thereafter came the phase where I have named the parts and she has picked out right from the heap. Of course, the parts with dog, cat, tractor, horse, the absolute favorites. With about 15 months, she was then put in a position every 10 parts immediately to the correct position in the puzzle. It has thereby given to push the parts into the gaps in a lot of trouble, which you do not always succeed but using. Have we then used together all the parts, there was applause and she has been looking forward to. She is now 17 months old and for them it is no longer a problem to put the parts alone to the right place. It is even so that they typed into the respective gap, to raussucht the right part and independently targeted uses and then applauded themselves. Quality is great, it looks despite daily use, and falling to the ground every day and occasional trodden still like new!
I therefore recommend that the puzzle every infant from about 12-18 months.
