We bought this for Oliver when he was 29 months old, and at the beginning it was quite difficult, so much he never wanted to do it without our help. But after just a couple of weeks, one day I was putting Emily to sleep and had asked him to wait for me in the living room and play by himself. It took a bit longer than usual for Emily to fall asleep, so I was expecting Oliver to come for me, but instead I found him sitting at his desk working on his puzzles (“Oli working”, he says) until he had the three of them done.
This is the power of concentration—something we’ve always worked on at home, and that has been reinforced beautifully at the Montessori school—that happens when the difficulty of the toy and the interest of the child are in perfect sync.
