You would need to supervise your child at all times as the alphabet letters are small and the magnets don't always stick. It is flimsy and would not withstand hard knocks well, which is needed for children of this age, but with care would last a reasonable amount of time.
Would need to be much more durable for me to attain 4 stars and letters need to be bigger with better magnets so they attach every time.
Not great value for money.
