My favourite toy is 'blocks'. I played it since young but back then it was only one wooden colour. Now it has more colours on the wood. I love blocks as it helps enhance my imagination as I build something. And you can play it differently. You can stack the blocks up and see how high they can go. You can learn colours by grouping them into same colours. You can learn shapes and sort them out too. You can also use the blocks to place on the paper preventing the paper from flying away due to wind. Blocks are so multipurposes! I enjoyed playing it with my sister when I was young.
Now I play blocks with my children. It is the toy that they can spend longer time in. And I see they materialised their imagination into what they build. And it is certainly awesome children-parents bonding time.
Parents who play together with their children will learn more, grow more and younger in brain. Haha. So definitely blocks are my favourite toys.
