I bought this little magnetic board and magnets about a year ago, to begin with we kept it just above the art shelf but it wasn't a good spot and so I moved it to the little shelf in his bed, this turned out to be the perfect spot. Every night as part of the routine, he changes the date for the next morning, has his milk and I read him a story, often he will read a book or put on a CD and go to sleep. From this simple little routine he now knows all the days and months. Love it.
The only rubbish thing is that February is spelt incorrectly, grrr.
